Hello everyone,

I've been following the CHDK and Magic Lantern development for some time, and I must say, what you guys did with the 550D (T2i) is amazing.... so amazing in fact that it might be the perfect solution for a project I am working on. 

I need to shoot anywhere between 5,000 and 100,000 images per "cycle", which is something I usually do with framegrabbers.  This would obviously kill any DSLR in less than a day. 

My need is to shoot at various exposures (HDR) with external triggerting without killing the camera. 

So essentially, I would like to use HDR bracketing, LCD sensor, mirror lock up,  AND electronic shutter altogether.

I've managed to get the HDR bracketing triggered with the LCD Sensor (love it!), so I can put some electronics there to automate the acquisition, I tried the silent picture and mirror lock up, but I can't seem to find the way to take pictures without triggering any mechanics (maybe its the liveview? automatic setting in HDR?). 

The setup would be static (no need to refocus or do anything else other than taking pictures)  Lighting could vary but be compensated by various EV stops in the HDR bracketing and fixed in post.

Also I was reading on the main page that the silent mode is limited to 2 megapixels, but in the menus I see more resolution when doing 2x2, 5x5, etc.. is it a lack of update in the features list or am I missing something?

Thanks all!

How do I force the mirror to NEVER flip between shots when using interval timer?
my tripod is ultra hyper sensitive to oscillations and i have to wait 15 seconds for it to finally become stable and the mirror flipping causes my images of the stars to look like all the stars are duplicated vertically and smeared by like 50 pixels!

I'm also doing this untracked. camera set to prime focus with a telescope. I still need a field flattener for a cheap 70mm F5.1 refractor telescope cause its a bit fuzzy toward the edges to improve the sharpness at the edges because the view is so wide.
so I need to catch as many frames as possible in quick succession without the mirror flipping causing crazy camera shake.
the first frame looks sharp but all other frames dont because even if i try the best combination of options for mirror lockup "always on" and using interval timer the mirror will start flipping up and down for every frame and i cant get it to stop!

How do I make the mirror stay up aside from pinning it up with a toothpick or some object??

Good morning,

Does anyone have any idea to run my 70d?
I was at the concert yesterday.
I took pictures and recorded videos for 5 minutes.
Suddenly, the camera hangs after you finish recording the movie.
The video file has been saved correctly.

I have an SD card magiclantern-Nightly.2018Feb17.70D112.
I recorded the movies normally from the Canon menu.

The camera will not turn on.
No messages on the screen.
I tried to remove the SD card and battery.
The LED blinks once only when inserting the batteries.

After removing the lens I found that I have a raised mirror and a curtained shutter - no matrix is visible.

#5
I don't take any pictures with my camera, not at all. All i do is video recording. As my job requires it, i have to turn it on and off pretty often (also to preserve the battery).

So I don't want the mirror to move when I turn on and off the camera. To me it's just eating precious shutter life. Can you force camera to make the mirror stay the same all the time?

#6
I would like to remove the mirror in the 50D to be able to use cinema PL lenses for Raw shooting. I know that is possible. Is there someone who has attemp to do that with success. Thanks.

hi guys, i just want to ask, my eos 60d now stuck...
overall until today i use magic lantern, was good.
but tonight, i try to invalometer on, i testing on 30", Manual mode,
i want to stop it, but dont stop, so i turn off the power..
now my camera dont want to shoot, if i shoot, mirror was lockup, bout 20 secs. and dont take a picture.. :(
but my camera can take a picture use live view or greenbox(auto), and mirror was not locked up till 20secs..

i'm very sad,, about my problem.. i just shock, so i try to update canon eos 60d firmware to 1.1.1,
but still same the problem :(

anyone can help me? pleasee.. :'(

thank you,
ingrid.


======
SOLVED.
after i update canon eos 60d firmware to 1.1.1, i unplug the battery out bout 10 secs, but still same.
so i clear all camera setting *again*, testing with live view shoot 3-5times,
and i unplug the battery about 10min, now back to normal... :)

Feature Requests / ND filter instead reflex mirror
April 30, 2017, 02:25:22 PM by domasa
Camera EOS C300 has three internal ND filters:

ND 0.6 – 2-stop reduction
ND 1.2 – 4-stop reduction
ND 1.8 – 6-stop reduction

This is better than screw and unscrew ND Variable filter on lens after each change of luminance (filming in the dark church/sunny garden before church).

I use my 5D Mark III mainly on video. Why not use dark ND filter instead reflex mirror8)


Would be possible control reflex mirror in video mode? (flip-up/flip-down)

If yes - some company could be create ND filter (like "Mosaic Opto-Electronics, Inc." creates VAF filters)  :)

Reflex mirror replacement should be relatively easy:

takes one photo then stops why it says intervalometer stopped
why cant i do 0.5s delay for mirror lockup always on + intervalometer set to crazy pics per second?
I want to do this for astrophotography and stacking images but it just WONT WORK
it works if i change from single shot to 2s timer or remote shooting but i dont want an extra 2 seconds or 10 seconds of delay between shots cause then i cant get as many shots as fast
and im doing untracked so it wont work having a longer delay.

it also locks up my camera until i turn it off and back on. I cant go to magic lantern settings. turn off the display. or go to the menu settings nothing happens when i press the buttons

Feature Requests / Mirror Lock-up
November 16, 2017, 06:02:42 PM by garry23
Currently we can control Mirror lock-up in two ways.

Always on responds as per Canon, i.e. Two shutter presses, with the first 'just' moving the mirror.

The second being a delay when using the intervalometer.

Some other cameras allow the shooter to select a delay between the mirror going up and the shutter activating; thus reducing mirror vibration issues when not in LV mode. 

So a thought. Can we introduce a user selectable delay in the ML mirror menu, say in 1/10 sec up to 1sec.

And/or bring in mirror control in Lua, unless it's there and I've missed it. My idea being, via the shutter property and/or keypress event, control the mirror and shutter through Lua.

#13
Would it be possible to lock the mirror up between exposures when shooting HDR still images?

This would reduce wear and tear on the camera, possibly increase the battery life a little and reduce camera vibration and movement between exposures.

#14
Hey all, thanks for a great product and a very helpful forum! I tried searching but couldn't find an answer to this: is it possible to enable mirrored/reverse LiveView on an non-flip-out LCD camera? I have a Canon 500D and I use a flipbac device to view the screen. It's a mirror that attaches to the bottom of the lcd so I can look down while shooting and see the display, since my camera doesn't have a flip-out LCD (my ghetto cheap alternative). Is there any way to enable the display options to reverse the image so it appears normal in the reflection? I saw this option is coded into the ML for other cameras, is there a way to activate it in mine? I have the option to enable Upside-Down mode but that's not exactly what I need.

#15
Hello,
Sorry for my bad english and for my bad knowledge about filmographie.
I think it would be great to only close the mirror on clicking on Liveview (to reduce the shutter count, especially for Timelapses), but the curtain should be closed (to not overheat the sensor). It would be great to also not close the mirror on changing Modis.

Hi,

I have a Canon EOS600D with Magic Lantern for about a year and it worked always without problems.
Today, I wanted to do some filming. Lens attached is  a Canon EF 50mm 1:1.4.
As I was in movie mode, I changed the follow-focus setting in the ML menu.
From that moment, the LCD display turned out black and the camera didn't react anymore.
I turned it off but the mirror stayed in the locked position. Same thing for the diaphragm of the lens.
After that, I removed the battery and the memory card but nothing changed after reinserting the battery with or without the memory card.
I put another lens on the camera : nothing changed. The diaphragm of the 50mm lens remains closed event when detached from the camera.
I tried to restart the camera in all dial modes without succes.
Does anyone has another suggestion to unblock my camera? Is there an undocumented feature (key combination) to reset the camera?
Any help would be highly appreciated.

General Help Q&A / LV without Mirror Up
April 09, 2017, 11:55:46 AM by garry23
@A1ex

I have a use case that ML may (sic) be able to help with.

As a stills photographer I don't always use LV, ie I use the eye piece a lot.

I often find myself wishing to focus at the HFD, but to do this I need to switch to LV and use ML feedback or scripts I've written to automatically move the lens to a specific HFD state, eg fully open, optimised for DoF or sweat aperture (open + 2 stops).

One thought I've had is explore if ML could allow me to drive the lens with the mirror down (sic), ie I'm using/accessing the normal eye piece functionality/feedback.

My idea is to use a script and allocate this to a key of my choice, thus allowing ML (if possible) to drive the lens to the HFD whilst I look through the eye piece, ie composition is the one thing I wish to control.

I've explored the current lv functionality in Lua, but this doesn't help me.

So the question is, could ML be used to allow the AF drive, whilst the camera's mirror remains down. Or is this idea simply 'silly'.

I appreciate this is not top priority at the moment, but I would like to know if it is possible in principle.

General Help Q&A / Mirror wear
January 07, 2013, 06:32:16 PM by canaldin
Hello,

I always wandered why there is no more the possibility to make time lapse with regular jpeg images as shot by the camera without moving the mirror. I may be wrong but I remember doing hdr timelapse with no mirror movement with regular jpegs, this can significantly reduce the mirror mechanisms wear. I looked into the silent mode but the whole workflow and limitations made me feel kinda crippled in what I was doing, file rename, lo-res, lcd always up and so on. What do you think?

Feature Requests / [IMPOSSIBLE] Mirror ALWAY up
October 01, 2013, 08:30:58 PM by TLSA
Hey guys.
OK so this is my 1st post here. I was shooting Canon for years and then in 2010 went the Nikon route. I am now back at Canon with the main reason being ML.
I was wondering if if would be possible to get the mirror fixed in the up position when shoot timelapse - in other words the mirror stay up and only the shutter open and closes.

#20
Is it possible to take pictures for a timelapse without having the mirror to move between every pictures aka take silent-ish pictures? I noticed mirror lock up has "self timer" as option, what does it mean? I wasn't able to lock the screen. Not even live view.

#21
How about features to help conserve actuations and power drawn by liveview (i.e. backlight) between shots?

Imagining a full day of shooting video, I'd love to be able to lock the mirror whenever the camera is on, but with my control over whether liveview is drawing power. This way I can power down liveview to save power, without feeling like I'm burning actuations unnecessarily.

Basically the suggestion is a RAW video mode where each of 'standby', 'preview' and 'recording' states are power-optimized, and transitioning between them does not involve the mirror.

How aggressive could a 'standby' state be without turning off the camera?

#22
Hello all,

Currently when setting up a mkIII and previewing the image (live view), the mirror will only stay locked up for 30 minutes.  At 30 minute, the mirror slaps back down and I can no longer monitor the scene.  I'm wondering if there is a way in ML to keep the mirror locked up indefinitely?

Basically, I want to use the 5dMKIII to feed an image to an external recorder/switcher and not record anything to camera media at all.  I can get it all set up and feed an image to the secondary device through the HDMI out, but at 30 minutes mirror slaps back down and my image is lost.  any ideas?  Thanks!

#23
First i want to thank for the voluntary work on developing Magic Lantern, it really improved my Canon 7D. 

Now to my issue:
On most of the newer canon cameras you can choose "Silentmode" during liveview operation. With this setting set at "mode 2" the camera uses an electronic first shutter curtain to make pictures.
I realised that with lenses longer than 200mm at exposure times > 1/300s images get considerably sharper when shot in  silent mode compared with mirror lockup. At really long focal lenghts the difference becomes drastic. The reason for this observation is that mlu prevents the vibration caused by the mirror but not by the mechanical shutter movement, so even with mirror lockup feature there is still significant vibration during exposure.
Since I realised this effect, I have used liveview to take wildlife pictures in order to get the full sharpnes.
But shooting telephoto lenses with liveview is very inconvenient, especcialy because you cant use the fast autofocus (allways turning liveview on and off is clearly not feasible).

So in order to improve the mlu feature I make the request to add an option for "shutter lockup". In the most simple way the camera would automatically switch to liveview after locking up the mirror, take the picture after x seconds and turn livewiev off.
But maby you folks know even "cleaner" solutions?

Best regards,
Meik

Hardware and Accessories / T4i Mirror remove...
October 14, 2013, 06:14:23 AM by radioman193
I ONLY use Live view and i find the mirror a Big wast ot time and dont like the camera shake and all that Extra NOISE.

i have been thinking of modifying the camera by REMOVING the useless thing ...

what are your thoughts in a mod like this ?

#25
Using a 700d. When i set the intervalometer (5s intervals) with silent shoot enabled in live view mode, it takes about 6 pictures before the mirror flips down due to being idle. Then it won't take any more pictures until I touch a button to bring live view back up. I feel like I must be missing something obvious, but I looked through the userguide, FAQ, and searched the duplicate questions and could not find anything about this.

Settings

Intervalometer
-Take a pic every 5s
-Start trigger leave menu
-Start after 5s
-Stop after disabled
-Manual FocusRamp OFF

Silent Picture
-Silent mode simple
-File format DNG

Sorry for the noob question. Thanks for any help you can give.


#26
Forgive me for not reading through every single message possibly related to this.

I want to do the following:
• Use an Arduino controller to move stepper motors and pass 400-1200' of 3-4 perf film through a gate, illuminated with a RGBW LED lamp.
like this: https://www.magiclantern.fm/forum/index.php?topic=25117.msg228255

• Mirror Lockup to avoid vibration and keep it from flapping around
https://wiki.magiclantern.fm/userguide#lcdsensor-remote
https://www.slrlounge.com/capture-sharper-landscape-detail-by-using-the-mirror-lock-up-feature-in-your-dslr/

• Use the 5D as a film scanner at max (2-4) FPS — without triggering the DIGIC buffer overflow to shut down.

• I'd like to avoid the MLV format altogether, and instead pass the full CR2 raw file (5616 × 3744) data back to CF Card, preferably as a CDNG, but that's a big ask.
https://forum.blackmagicdesign.com/viewtopic.php?f=3&t=28920

It seems this has been done in parts but not all at once. Am I missing something critical in the forum history?

Thanks in advance!

what camera? i don't think you can shoot jpeg untethered without moving shutter/mirror. the jpegs are small anyways. better off using the 4.22. you can convert them to whatever you need. with movie sizes they are ~hd. shooting a movie for timelapse isn't bad either.
Untethered? Are you saying there is a way to do this tethered?

#28
Hello Team,
I recently started using magic lantern and the first shoot was to create a timlapse video, the output was awesome and it worked as expected.
I was just wondering that the intervalometer doesnot work when I use the mirror lock function. Well what I mean by that is if I use mirror lockup function, it stops flicking...
One thing that came to my mind is that why the mirror has to fire everytime its taking a shot, why cannot we just lockup the mirror and keep taking shots via sensor, I am not sure the mechanical movement of the mirror is required everytime...
It will do two things, increase the shutter life by stopping the unnecessary firing and second is that the battery utilization will also reduced...further, it can minimize the motion blur caused by the mirror.
Help me if that sounds good or ridiculous to you!  ;)

Cheers and keep rocking magic lantern team!

Feature Requests / 5Dmkii Mirror Lockup Burst Mode.
June 14, 2013, 08:37:46 PM by Doyle4
Was wondering as RAW Video has been accessed, the 50D 5Dmkii and 3 seem to have best potential due too memory card speeds,
so i was wondering if there was a way of making a mirror lock up burst photo mode?

RAW video can capture 25fps upto 1880, can dropping the frame rate way down allow higher resolution to be captured?

As the mkii shoots at 3.9F/S with the mirror, is it possible to be able to capture say 6fps? or even 8 without use of mirror but using the RAW video method? im certain if it was possible full resolutions couldn't be done due to size of files in RAW, im not sure on jpeg as i hardly ever use it but say using small raw mode? (9mp).

Cheers  ;D

Hi !

I'm fairly new to Magic Lantern, so excuse me if this can already be done ...

I'm using ML on my Canon 5D2 to generate 7 frame exposure brackets for HDR spherical panoramas.

I have selected Mirror Lock Up and it allows a two second delay between frames, but it would be great to have three secs or longer delay to eliminate all camera shake when mirror goes up.

My spherical panorama head causes slight vibration and a longer delay option would really help ...

Is this possible ?

Also, is it possible to shoot the exposure bracket range in the same sequence as standard Canon firmware (on my 1Ds3) - Ie : Exposure at 0 and -,-,-, then +,+,+ ?

Thanks so much !  :D

General Chat / Flash Mirror on 600D
March 30, 2015, 10:42:58 AM by RobFlanders
Hi all,

General non-ML specific question - I have a flash mirror that mounts to my hotshoe on my 600D.

However, when you mount something in the hotshoe the camera assumes there is an external flash, and promptly disables the built in flash. Is there any way to disable this behaviour, so that I can fire the built in flash when there is something in the hotshoe?

General Help Q&A / Remote capture with mirror lockup?
February 14, 2018, 11:56:30 PM by kenreddick

Wondering if there is a way through USB to remote trigger image capture while the mirror is locked on a 5D3?


#35
Doesn't answer your Q but you might be able to shed some on mine. I will be using a basic shoot move shoot controller but wondering how I sync it with Bulb ramping.
I have been thinking that if the initial stop delay could be replaced by a simple signal from the camera.  This would just leave the move timer acting. What I was thinking is whilst ever the camera is outputting an LCD video signal the motor can move (withing its time set point and stop). As soon as the screen/mirror locks up the motor stops. Resets and then video comes on and the motor starts.
This video out signal idea cam as a result of test an external monitor today.

#36
I have some experience with a dead camera.
Last year i disassembled my 50D and ripped the button battery wires.
So, i tried to fit the black one into the connector once again and i thought it was ok like that.
After powering the camera up i could do everything within like 5 minutes and then the camera would suddenly lose power. Mirror would not come down and you could do nothing.
Turns out the wire wasn't fitted properly so the circuitof the time and date button wasn't closed.
The camera has some sort of protection and if this happens you should take both batteries out and leave the camera to discharge for something like a few hours.
Hope this is of help.

#37
I have had a previous issue with bracketing on my 60D if "mirror lockup" was activated in ML. 

Also, try turning off live view before taking the brackets.  I find that sometimes with LV on, it doubles up on the first couple of exposures.

#38
I think the best way to deal with this option is to choose f/5.6 for most of the time, and keep your camera in AV or Manual mode setting (in manual mode, you could select auto iso and still tell the camera to keep a example 1/100 shutter and f/5.6 aperture. simple!)

I personally shoot a lot using TV mode (for mirror lenses and other longer lenses and when I want to make sure that my shutter is fast enough) or I choose AV mode (for landscape, every-day-situation snapshots, etc.) and at times M mode for those times when I have time to play around and want to have a bit more control.

All those stuff stays the same whether I am using Magic Lantern or not.

General Help Q&A / Re: Compatibility with DSLR Remote Pro
February 04, 2013, 06:48:12 AM by scrax
wasn't bricked if a battery pull solved it.
On 400D sometimes my camera get stuck using flash with low battery, mirror stay up and a battery pull solve that. But I still use flash and batteries till that happens  ;D

I don't know since no OTG on my phone, maybe you could ask the dev of the app to test it first, if he has a ML supported camera.
But have already tried ML controller already? It's made with ML support and can so control some ML features too.

#41
Check out the Handheld Mirror Lock up feature. You can configure the time delay.

Thanks, it appears to be tiny bit more expensive here in New Zealand but it's not too unreasonable, I guess. Does the mirror flick back-and-forth if I use bulb-ramping, which seems to make use of live-view?

Turn off Flash/No Flash which alternates taking shots with and without flash.
It works, which is really great. At least, now I can use it as a backup body for studio work.
Just one thing makes me uncomfortable - T2i/550d makes a lot of "noisy clicks" in this configuration.
I have another camera 50D and it doesn't use prism/mirror in Live view mode at all. It means, when I turn on LV, mirror goes up and stays there.
T2i - turn LV on -> mirror goes up, press half button to focus -> mirror goes down, press full button -> mirror goes up and down, release button -> mirror goes up again. So, for only one shot mirror makes two whole cycles. I am not a pro, but I think this body won't live too long for this kind of usage.
Anyway, I am happy to get ML on my camera.

Not all of this is implemented; should be straightforward, but a bit time consuming. Anyone would like to help me?

General Development / Re: FPS/ Shutter actuations

I can think of a hardware limitation for the 1000D which (i'm counting on my memory now) had a mere 1.5 fps burst. Considering the same shutter and mirror assembly as the 450D, i guess that was something in the FW that prevented a better performance.

Actually no, the 1000D has 3fps burst in JPEG. It's artificially limited to 1.5fps in RAW.

Is there a way to 'mirror or flip' the image while filming with Magic Latern?  I want it to be like the inner camera on an iPhone or 'selfie' mode.

#47
From what I've read, $150-200 in the US for shutter/mirror-box replacement, depending on model. These might be CPS prices (only if you are a registered pro).

I really like the automatic mirror lock-up feature.  When I'm shooting portraits I set it to "handheld" and when I'm shooting landscapes I set it to self-timer.  It would be really good to be able to set it to "handheld and self-timer" so that it would work either if the self-timer is enabled or if the shutter speed is 1/2 - 1/125.

Feature Requests / Mirror/reverse display
July 08, 2013, 04:19:09 PM by aamf
It would be great if the live-view display of cameras without a flip-out screen, such as the 5D mark II and III, could be reversed and/or mirrored. This would make it possible to shoot from the hip using a small external mirror such as this: http://flipbac.com/angle-viewfinder-about.htm

Currently there is an option to display the overlay graphics upside-down, but not to mirror or reverse the entire live-view display.

"Mirror Lake" Canon 50D Raw Anamorphic - 4:3 at 1344 X 1008

For this video, I shot with a faster CF Card (100 MBS) that gave me 1344 X 1008 resolution at 24 FPS in 4:3 mode without skipping frames. I could shoot for at least 6 minutes (I didn't try shooting longer). I did my color correction with Adobe Photoshop and converted to 2688 X 1008 in Compressor for Vimeo. Anyone else shooting in 4:3 mode? Can resolution go higher than 1344 X 1008? Thank you.

Feature Requests / Night Scene mirror lockup
February 15, 2014, 09:19:51 AM by Denisad
I have the 700D and am particularly fond of the Handheld Night Scene mode. I know that queries have been made regarding the possibility of using mirror lockup for exposure bracketing but am not sure whether that has been ruled out or not. I find the Night Scene mode very effective and would love to be able to use mirror lockup in conjunction with it.

Hi,

I don't think this has anything to do with Magic Lantern being on installed but I reckon you guys are experts enough to read the log correctly. This is one of the logs, I haven't checked all of them and can post more if needed.

http://justpaste.it/logcrashML

I think this is probably the problem :
1327: 2603.984 [CAPD] ERROR [LV] Image Power Failure

The error happened after the camera spent a whole night and the next morning in its bag in the trunk of a car under a hard sun. I picked it up after noon and problem appeared right then.

I have tried to remove and boot without card, change batteries, clear C.Fn, clear all settings and nothing works. I don't know if there are any software related thing I can try. I would just like to know EXACTLY the nature of the problem to know if I should repair it or move on to another camera.

Thanks guys.

General Help Q&A / Mirror HDMI Out
November 13, 2015, 08:38:20 PM by melicjus
Is there a way that I can mirror (left to right) the image coming out of the HDMI? I am recording someone writing on the opposite side of glass and am trying to use a blackmagic ATEM switcher to put live overlays on that image but in order to do that I need the live video feed to be flipped coming out of the camera.

Thanks!

#57
Hi!

I have some Canon FD primes that has been converted to EF. I use them on 5D3. The 50mm has the glas so close to the mirror so it often conflicts while rising or lowering. So I wonder is there a hack to lock the mirror upp, even while can goes in to idle mode?

Best,
David

Feature Requests / Full LCD mirror transformation
August 10, 2016, 12:57:16 AM by garry23
At the risk of upsetting the moderators, I'm requesting this feature here, as I realize I posted the other day on an old post.

The use case is is when you are using a fipbac mirror on a fixed LCD.

In this situation, the flipbac allows you to see the LCD screen, eg from above the camera, but, of course the mirror image is just that, mirrored.

The request is to extend the existing ML feature, that flips the ML menu bars, so that the ML menu bars and the LCD image are fully mirrored, so that the reflected flipbac image looks normal.

#59
Although it was perhaps "never intended" but using bulb mode with handheld does not work.

The mirror will quickly move up, and the picture will be taken.

Technically it should wait at until the button released.

Should the anti-shake MLU should check if bulb mode is activated or perhaps it will be easier if we switch to another kind of MLU function?

Antishake MLU works splendid to up to 30" seconds. It also works quite well with shutter speeds slower than 1/2. I've been able to take a few pretty "shakefree" pictures as slow as 0"4.

There is a method for clearing dead pixels on some Canon models that you might find online. I believe that doing a manual sensor cleaning through the menu (as if you were physically cleaning it) can somehow fix dead pixels. Is it crazy or unheard of to have 2 dead pixels on a brand new camera? No. Would I personally return the camera? Probably. In normal use this will have no real effect. It is easy enough to fix those 2 pixels in post if you need to print or post at full res but almost any use is going to involve downsampling.

As for the menu you are correct. There are less tabs in 2.3 than in previous versions but the same number of options.

like quote before i going to donate u guys in moon.day..i love to have that full version even is less stable ..
abotue sensor cleaning..i use this Half Auto Method ... and later some small swab dry thing ...
that method with open shuter not fix dead points on sensor..it make it  looks liitle more bright ..still dots stay on ..
i use later some small swab.. i touche gently places where i  sean that dead places...
:DD ... i killed one Dead Pixel :)  ...one is gone. im not sure for how long..or maybe its depend of my camera setings and and and or or..ect ect..
i dont realy like to doing this stuff with swab again..cus i know how optic is sensitive..i use telescope and analogs alot years and once i was try to clean Telescope Main  mirror... LOL with Washing Liquid  O_o ... bad..very bad..
i i tuche just little.. and i killd protection on mirror..

i doing alot things  in graphic 2D ... this red nasty dots are not Extream Problem. cus i can remove it in Photoshop in 0.000000001 second ... but my motto of making photos is like :...`` Make photo and make it looks perfect with OUT EDITING or Extra software ``...

so with this dot is loosing little sense..

i will try post full resolution by uploading my  shots to DeviantArt ..yes this is best choice..DA dont change quality or resolution..

,,,one more thing..

after cleaning with swab i was lost one red dot but i pick one more White one :/// ... i knwo why cus dot changing places  on photos and still is smae shape.. looks like small swab left some tihng in side .. not problem this is .eazy to remove  it s .. not eazy as  dead pixels.



#61
Yes. that did the trick. I will have to run a few more shots because I kind of thought they all looked a bit weird from a flash-wize-perspective...

[Edit]

Everything seems to work ok, even with the built in flash. Will try and see if 5d2 acts different... 

[Edit2]

With 5d2 and 580Ex II, there's a tendency that the flash does not go off at every picture taken. Possible culprit is recharge.

Further there's sometimes two pictures taken instead of just one, with a few seconds interval between the two and also shutter sometimes halts in the mirror up mode, which forces me to press the camera once or turn it off.

I also noticed that the flash made two unexpected flash exposure reading operations after turning on camera and flash. It should not do anything. I could not reproduce the latter, the others are reoccuring from time to time.




#62
I believe there is a silent mode but it doesn't capture at full resolution.

I wish I can lock up the mirror forever (like how in the old say with the Olympus OM-1), and so I can kept my camera more steady.

I WOULD LIKE TO HAVE A PEN

I would like to have a pen, but not any pen...

a pen to describe the peoples face inside the bus in the way to work... each expression, the sadness in the eyes due to life is not the way they would like it to be... the lines drawn in their face by the bus motor noise everyday hurting their ears made to listen birds singing...

a pen to expose my emotions when everybody tells me to hide them...

I would like to downgrade my pen sometimes for a pen-cil to have the option to rub the paper vigorously after write a mistake in my life, erase the missed opportunity and rewrite it into an orgasm of happiness

I would like to have a pen-is not to cum for porn dreaming about girls I will never have, but a pen-is to write in my girlfriend's skin how much my heart pulses for her... hoping the ink cum would last forever... just like a tattoo...

I would like to have the courage to exchange my beloved DSLR for a hacked pen in which the ink would be automatic multicolored changing taking into account the the meaning hidden between the text lines...

I would like to have a pen which could draw a movie in an electronic paper to avoid me the hard work to turn my ideas into a feature film and this way I could celebrate my sinful sloth

I would like my pen to be a sharp knife to hurt the film emulsion just as the film emulsion sometimes hurt us and make us cry inside the movie theater... and this way my sharp knife pen would write the story direct into movie images just like Norman McLaren did.

I would like to have a pen and some pieces of paper to make this writing task my lonely work to avoid the need to beg people to help me mainly when my sweaty money is not enough to pay for their willing

I would like to have a pen to tell how much Mary waits for John everyday in the bus station twisting her hopes for he to stop just looking and take the action

So my pen could tell that John can't imagine Mary looking to her mirror to perceive if her beauty is enough to make him overcome his shyness and make the move

And my pen would find the words to make people imagine that mid age woman with her shining eyes in a hopping face when she sees the young lawyer inside his black suit up the bus stairs and stand by an old washed out advertising of the Nothing Hill movie.

My pen would have the power to describe the angels taking care of us hidden against the sunlight in the sky where the DSLR poor dynamic range could never see them... and they just laugh about the joke God always do not giving each one of us our operating instructions when we was born

So my pen could write the second life many people would like to have forgiven the beloved partner instead of breaking up...

I hope my dreamy pen do not stop taking the virginity of paper and makes me more happy than my never perfect DSLR

and I also hope I do not upgrade my pen into other tools to avoid turning myself into a forum member to discuss voice recorders, computer keyboards, writing softwares and printers.

Does it say anything about taking pic? The event 80001 is in the list and should be recognized.
Ok, here's what happens.
If i press the shutter button 1010002 80001 200 is shown and it says  "taking pic". The fact is that the mirror IS taken but it waits a looooong time before doing so. 30 seconds, in fact, and i don't know why.
So the mirror is raised, shutter is still closed, 30 seconds pass away and then the picture is taken as it should.
I'm shooting with an all manual lens, by the way. The problem seems to be the delay.

#65
As for getting it repaired by Canon, ask them how much it costs. Contact their service department. From what I understand repairs are relatively cheap and turnaround times are fast. A new shutter/mirror box costs $150-200 depending on the model, so I can't imagine a mic input being very expensive at all.

#66
Most people don't shoot photos in LV. LV doesn't do the same thing either, it drops the mirror. Look through the VF, you'll see it.

#67
I did on my 5D2. It doesn't drop the mirror.

#68
That mirror adds a lot of shake. Also it probably takes care of anticipation issues/etc. Just like with shooting a gun.

Quote from: a1ex on October 22, 2012, 03:44:33 PM
For longer delays, use the self-timer option (2s or 10s) - only one click.

That's true and with a rather annoying blinking light as a bonus.

I know.. I can do like Canon and put some scotch over it.



Did some more tests yesterday and was able to get decent handheld shots at 1/60 iso 6400 800mm f/8 evening/night photos from across the street. I was also able to get pretty decent 1/4 iso 100 50mm f/2 indoor shots without much shake.

Two examples:

Iso 3200, 1/100 f/8.0 800mm mirror lens, hand held.

#70
Done some quick tests with a 800mm mirror lens and shooting at a target around some 5 metre away and come to the following conclusion.

No matter what shooting style, live view gave a slight edge of sharpness in my test...

1 ) Photo
2 ) Photo using live view
3 ) 2 second delay
4 ) 2 second delay with live view
5 ) Remote control photo taken
6 ) Remote control photo using live view
7 ) 10 second delay
8 ) 10 second delay with live view
9 ) Mirror lock up (Canon) 2 shutter presses
10 ) Mirror lock up (Canon) live view
11 ) MLU - 1 second delay
12 ) MLU with live view - 1 second delay

The 2, 4, 6, 8 are all sharper than their non live view counterparts.

I perceive the differences between 9 - 10, and 11-12 as somewhat smaller than the differences between other counterparts, this despite contact with the camera in order to activate the functions.

I got the impression that the remote shooting with live view gave the sharpest result, followed by a 2 second delay, and the mirror lock up and all the other live view photos. It's harder to tell which of the ordinary photos that was sharper but I perceived 1 and 9, 11 as quite similar and probably amongst the sharpest ones, most likely due there's not much difference from pressing the shutter one time, or two times (as long as there's long enough pause between the presses).

#71
Well in modes other than P I sometimes get your problem and the mirror stays locked until you press the button again. So interception isn't QUITE perfect.

General Help Q&A / Re: Mirror wear
January 07, 2013, 06:45:56 PM by 1%
what camera? i don't think you can shoot jpeg untethered without moving shutter/mirror. the jpegs are small anyways. better off using the 4.22. you can convert them to whatever you need. with movie sizes they are ~hd. shooting a movie for timelapse isn't bad either.

#73
Ok, 2 questions for you based on what you just wrote:

- What's the Liveview raw buffer data structure? uncompressed? Raw? Jpeg? What do you mean by "image quality is limited" other than resolution? I'm using a 550D.  Now that I think of it, I guess it doesn't use the ISO setting I've set the camera to right?

- Is there a way to keep the mirror up between exposure? Worst case scenario I could always detach it from the camera once it dies if that's the only show stopper...

#74
Yes, that's true. Canon requires two presses, which makes ML superior.

Canons model works in an old manner, you press once and decide when to take the picture. I suppose wind , lighting conditions and other stuff might have been the reason for two presses because that way you could measure the scene, and pretty much just wait until the breeze has settled or that "right light" is there/bird in the frame, or whatever...

As long as there's a pause value large enough on ML, it should pretty much everything one can ask for.

Stretching the feature further is probably not possible due the mirror lockup/lack of measure possibilities..

I've just done some quick tests, with a sigma lens that has image stabilisation and without the stabilisation and the MLU feature and somehow got the impression the MLU is better. But needs more testing.

#75
Just tried and if i enable all it does is raise the mirror as i press the shutter. I have to press it once more to fire a shot. Something doesn't work.

#76
Silent picture writes the liveview buffer to a file, so you are limited by that buffer size. Needless to say, image quality is limited as well. The hi-res mode works on some models, like the 550D. There is no other way to take images without using the shutter. Mirror lockup is not intended to hold the mirror up between exposures.

#77
Well, it has mirror lock up. Not very hand-holdable, but...

There are quite a few articles on it. I stumbled on it when I first started shooting with mirror lenses...

5D2, C.Fn III: Autofocus/Drive Mirror lockup 0/1 - Disable or Enable
550D, C.Fn III: Autofocus/Drive Mirror lockup 0/1 - Disable or Enable

http://www.cameratechnica.com/2011/04/26/dslr-mirror-lock-up-worth-the-effort-or-not/
http://www.bobatkins.com/photography/tutorials/mlu.html

#78
Tried taking some photos on the fly. It's a bit smoother than the built in Canon feature, but I noticed that sometimes the picture is not taken.

When using a Canon 550D, 0.1 seconds and trap focus, I noticed that sometimes the mirror lock-up would occur, but no picture would be taken until i pressed the shutter.

When changing to 0.2 or even 0.5 seconds the mirror would lock up and a picture was taken and then returned to normal mode without further interaction from the shutter button.

I also noticed that the mirror lock-up would not occur, unless I turned autofocus off from the lens and no picture could be taken, until the autofocus got turned to manual focus on the lens.


#79
The mirror doesn't go down in liveview though, at least on the 5D2.

#80
so,
1. only auto mode and LiveView are ok?
2. In M, Av, Tv, P you have the mirror lock up problem?
3. Movie mode works?
4. C, CA works?
5. without card can you take a pic without problems?

Hi all,

Thanks for your great job and really happy to hear that things are on a good way.

I used a couple of 60D in tv documentary production for one year with great results. I would never have tried that without ML. Now I would like to switch to my brand new 5D3 !

All you can do is highly appreciated but here is what is most important for my video use :

- Analog audio gain control with separated values for each channel.

- Audio graphic monitoring in the upper black part of the screen like others ML. Canon implemented one indeed but so badly located and small!

- Possibility to adjust the audio output level - essentially louden

- Same iso treatment as ML 2.3

- Expo override 1/25e

- Zebra, focus peak, histogram, magic zoom, discrete virtual horizon

- Possibility to flip the screen vertically and/or horizontally in order to use a small mirror system to compensate the lack of rotating screen.

All you can do to enhance video quality is also very welcome : higher bitrate, clean 4.2.2 on HDMI, HDR in 1080p25...

Just an idea/question : is it possible to make raid 0 using the 2 slots, with 1 sd and 1 cf of same capacities, to be able to record very high bitrate or fps?

Thanks again and hope to hear from you soon.

MF works everytime with the delay time set up in ML menu from locking up the mirror to taking the picture.


with AF enabled sometimes it works.....most of the time it doesn't. I can't reproduce everything that happens.

Pressing LV often just lets the lens focus then stop.

Or focus and MLU but not taking a picture--->only full shutter press makes the camera operable again and takes a pic.

and in 3 of 10 cases it takes a picture.

Ok, i just tested it and LV button is awkward to use and it'll prevent normal usage of LV. I have  tried BGMT_PRESS_FULLSHUTTER and it takes 2 pictures, or rather, triggers one normal shot and then another subsequent one where you have to press the sutter again to release the mirror.
SET is clear for me in photo mode (it can be assigned to a function, by menu, but i didn't) . The problem is that i shuold add exceptions here, right?  if (event->param == BGMT_LV && mlu_shake_free && !lv)
so it doesn't get triggered when set is pressed. Uhm, quite a long list, actually...
Quite a problem to assign this function to a button without triggering unwanted pictures but comfortable enough not to spoil the original grip.
Probably not so useful for middle range cameras as they don't recock the mirror in LV. I don't know...

However when I leave the camera at the video mode liveview, the mirror still lowers at 30 minutes, and then it goes back up and liveview restarts.  How can I stop that?  Isn't setting the sticky halfshutter already prevents this?  Or do I need to press the halfshutter once?
yep first time you press it it will stay pressed until you repress it when engaged you will se HR on screen for like a second before clean up (i've not tried it for more than some minutes)

Not sure if this helps, but if Live View mode is activated, the camera always shuts down  (in my experience anyway)

[Edit]
Actually this isn't right.   The info screen is blacked out and the mirror drops, but I believe the camera is still powered up as the USB connection isn't dropped.

I'll keep looking

Hi, TheCheatOSX. I'm sorry to hear about your night. Did you hear the shutter firing when you checked up on it? When you say it was still running, what do you mean by that?

If AF was on, the mirror would probably have flipped, then it would search for focus and it probably would have not taken a picture. The mirror flipping could have sounded like the shutter was firing. For a multitude of reasons AF should be off for timelapses.

Also, after the shot count gets to 9999 it will make a new folder. Is there any chance that you looked in the old folder, or that your card was full?

I've definitely fired off test shots, configured the intervalometer, and then forgot to turn it on before hitting the trash can button to start the process. Also I've left it on the "select a properly exposed photo" screen when bramping for hours... I find myself to blame far more often than ML.

#87
Yep im after something like this too(mentioned a few posts earlier). My sms is a simple ic555 circuit with relay so not sw programable. Is there any signal outputs generated by the camera after a shot, a mirror lockup etc that i can use to initiate the dolly motor?(instead of a set timer that wiould go out of sync with bramping). I dont have an mx2 or nanomoco. Raspberry Pi might fit into the equation some how but i have too many there projects im learning.

I've always considered shutter mechanism speed to be the cause of FPS for each camera. Memory buffer influences the number of consecutive shot that can be made at max FPS until full. But I've no proof on that only supposing this.
I can think of a hardware limitation for the 1000D which (i'm counting on my memory now) had a mere 1.5 fps burst. Considering the same shutter and mirror assembly as the 450D, i guess that was something in the FW that prevented a better performance.

#89
okay..... so for HDMI stream, I need to use the liveview mode.......

One more question: I turned on the Misc key->sticky halfshutter, turned off auto off (Canon menu), set the powersave mode to record only (ML) and turn off all three powersave items in ML

However when I leave the camera at the video mode liveview, the mirror still lowers at 30 minutes, and then it goes back up and liveview restarts.  How can I stop that?  Isn't setting the sticky halfshutter already prevents this?  Or do I need to press the halfshutter once?

5dc Port Progress
Current state: Open Beta



I started this project months ago, progress has been slow. The reason is that the 5dc is a bit unique. It runs VxWorks, but has a lot of similarities to modern DryOS cameras. As a result, simply porting Magic Lantern or 400plus was not an option, I had to start fresh.
EDIT The 5dc will work on the unified tree! Big thanks to A1ex for the help in making this happen.

Short-term Todo List:
Blink LEDs from user FIR file boot.
Enable bootflag for autoexec.bin booting.
Hijack Canon's GUI task.
Port BMP routines from ML for screen printing.
Port menu system from ML.
Fix fonts to be sized correctly on screen.
Fix up properties and property handlers from ML.
Begin porting all non-lv features from ML (intervalometer, audio triggering, trap focus, etc).
. . .
? ? ?

Install Instructions (READ FIRST!!!)
*** Remember, I am not responsible for any damage to your camera. This is BETA software, and I can't predict what could happen. If you are not comfortable with this, then please do not download this firmware. ***
1.) Make sure you are running v1.1.1 firmware (if not, upgrade to it!)
2.) Double check that you are running v1.1.1 firmware.
3.) One more time make sure that you are running v1.1.1 firmware!
4.) Charge battery to 100% and remove any battery grip for the install procedure.
5.) Download the zip file from the link below, unzip all of the files to your CF card.
7.) Launch the firmware update process. If you see any red led, then something went wrong. A solid blue led means that the bootdisk is now enabled. A blinking blue led means the bootdisk is now disabled (if you want to completely uninstall ML). Each time you run the firmware update it just toggles the bootdisk to the opposite of whatever it is currently. The installer FIR will make your CF card bootable for you, no further work required here.
8.) Turn the power switch off and pull your battery to turn the camera off. Just turn the camera on (make sure autoexec.bin and ML directory are on the card!) and you're all set. Press the Trash button to bring up the ML menu.

You only need to run the firmware update to enable the bootflag ONCE. Each time after that will only disable, re-enable, disable, re-enable, etc. the bootflag.

If you have any questions, please read the ML documentation to see if it can be answered before posting here:

Changelog / Release Notes

Beta 4 - 10/13/2012 (see also the announcement)

* All stability tests passed :)

* New stuff:
   - DOF bracketing ( http://www.magiclantern.fm/forum/index.php?topic=3113 )
   - Flash bracketing (not tested, I don't have a flash)
   - press DirectPrint to toggle MLU
   - RGB zebras and histogram
   - Display saturation (including grayscale preview - if you use UniWB, for example)
   - Exposure adjustment in playback mode (rough approximation)

* Complete feature list:
   - zebras, focus peaking, spotmeter, histogram, waveform, vectorscope (in playback mode)
   - exposure bracketing: shutter, ISO, flash; 2x0.5 ... 9x5EV; auto mode (covers the entire dynamic range).
   - DOF bracketing (changes aperture and shutter while keeping exposure constant)
   - Intervalometer
   - Mirror lockup (shortcut key, or link to self-timer)
   - Flash exposure compensation (-10...+3EV) - not tested
   - Flash / no flash (like in fuji 6500) - not tested
   - Display saturation (grayscale/normal/oversaturated)
   - Fast zoom (one click goes to 100%, like on 5D3/1Dx)
   - Quick erase (like on 5D3)
   - "Ken Rockwell" zoom (press Zoom In after you took a picture, without pressing PLAY)
   - Exposure adjustment in playback mode (very rough)
   - Timelapse playback - http://vimeo.com/48482815
   - In-camera help (press INFO)
   - Benchmark (check read/write speed of the card)
   - Display operating system internals (tasks, free memory)

Basically, this is what we can achieve on 5Dc with our current knowledge. For more, one needs to dig deeper in the firmware and reverse engineer it. The camera is about 7 years old if I'm not mistaken - but simply the fact that it runs a large subset of the same ML code designed for DIGIC 4 cameras, is amazing!

Beta 3 - 10/2/2012
Big thanks to Alex for this release! He found the missing VRAM buffers which enabled a lot of features in playback mode.

Working:
- auto bracketing, intervalometer
- zebra, focus peaking (huge help for this tiny screen!), spotmeter, histogram, waveform
- fast zoom in playback mode, quick erase (well... not quite perfect, but almost there)
- card and focus peaking benchmarks (5Dc's ARM processor is twice as slow as 5D3's)
- custom color palette for ML

Not working:
- RGB tools, bulb, trap focus, AF patterns (very hard or impossible)
- AF options, MLU (easy to fix, just takes time)


Beta 2 - 9/25/2012
- Changed boot code from how it's done in the ROM to how it's done in the firmware update flasher code. My camera boots, hope it works for all other 5dcs too.
- Updated to latest source tree, nothing changed for 5dc though.
- Now included is a FIR file that will only make your card bootable - just run the firmware update and pull your battery when you see the blue LED, your card is now bootable after that.


Beta 1 (initial release)
- Potentially very buggy. Try it out, let me know how it works. Many features are disabled because they don't work yet / will never work (obviously all LiveView features).
What Works:
- Intervalometer
- HDR Bracketing
- Flash Tweaks

#91
My quick list of candidates:

- Auto ISO limits in movie mode
- Picture style controls (same controls as with Canon menu)
- 60D level indicator (Canon has one too)
- Defishing (very rough in LiveView, although good in playback mode)
- Image effects (MOVIE menu) - they don't do any harm (they are simply DIGIC controls), but I don't think anyone will use them for normal shooting.
- Flash / NoFlash (I've used it on compact cameras and missed it on dslr, but now I no longer use it)
- Silent pics - advanced modes (I intend to keep only simple, burst and maybe matrix modes)
- Mirror lockup sync'ed with self timer (anyone using it?)
- Follow focus with LCD sensor (I don't remember anyone saying he used this)
- From Display menu: image position, orientation, upside-down mode (although they can be useful when you need them)
- Sticky DOF preview / HalfShutter (I never used those, except sticky halfshutter when running through DIGIC register). Trap focus no longer needs this.
- Some things from Debug menu (like tasks, CPU usage...) - but keep indicators with free memory and so on.

From that list, only silent pics is known not to work in matrix mode on some cameras, and I'll just disable that feature where it doesn't work. All the other things are working fine, but aren't that useful IMO.

You can come up with other suggestions too.

Removed:
- auto ISO limits (unstable, interferes with manual ISOs)
- movie remap (sorry for that, I know it was very handy, but causes stability problems)
- record with SET button (100% useless)
- ML auto ISO algorithm (was present in december version, but was too slow for real use)
- zoom in face detection mode (found to be unreliable, and couldn't find any use for it)

#92
I will be using a basic shoot move shoot controller but wondering how I sync it with Bulb ramping.
I have been thinking that if the stop delay period pulse could be replaced/triggered by a simple signal from the camera.  This would just leave the move timer acting. What I was thinking is whilst ever the camera is outputting an LCD video signal (ie between shots, the motor can move (within its time set point and stop). As soon as the screen/mirror locks up the motor stops if it has not already. Resets and then video comes on and the motor starts.
This video out signal idea came as a result of trying an external monitor today. Hope someone smart can run with this... or enlighten me of how to do it another way (preferably cheaply :)

General Help Q&A / Dead pixel...?!
July 28, 2012, 10:14:17 PM by axisvideo
Dear Alex and developers,
I had problems with the latest version of ML:
during some timelapse night in all the frames appear several pixels white and blue ... before the time lapse, in the test exposures, there were not. After i removed ML menu, test shots with Canon menu in high ISO values ??and long times 10 seconds, there are no dead pixels, what happen?
One suggestion if you let me: in the next release it would not be better to divide the functions of ML kind of interest, meaning you have to do a time lapse loads only the functions of the time lapse, if you have to do a HDR load functions for HDR, if you work with the video loads only the video features. May be this we could avoid the possible conflicts that seem to make but not completely stable ML. I do not know ...
Thank you,

Massimo
