General Help Q&A / Re: How to enable second funtions of top buttons?
« on: September 19, 2014, 02:46:51 AM »
It's part of Canon's efforts to cripple the "entry level" bodies so their 7D would look better, so no. There is no way to enable them. I don't know if you can enable it through software like ML though.

Feature Requests / Re: Panorama module?
« on: September 18, 2014, 11:17:29 AM »
I could think of a kick-ass combination of ML functions for the Brenizer method (or panoramas in general):

-Panorama module as described in this thread
-Full res silent pic to save shutter count  :)
-Intervalometer (with full res silent pic, this stores your pano in a single MLV file, which means you won't have to manually sort through your panoramas)
-Dual ISO if needed

No no, not all picture parts at all, I want only the current "neighbours" (left/top neighbour) while shooting - just to make sure, I don't move to far to get in trouble while stitching.

Hmm,, Brenizer correct - maybe we need a mode for this order of the pictures too. I never did that, but I think you shoot the middle picture with the subject first, and then go around. Correct?
Yup. I'm still experimenting with it but it's really hard to do without any "help", because it's very hard to tell which parts you have covered. If you have a gap somewhere in the middle of the end result (near the main subject), then the whole picture is unusable.

Actually I'm really interested in this too, for doing something like the Brenizer technique

I thought everything was good, but the fireworks didn't work for me...it doesn't quite fit into the video somehow. The sunset was kind of a natural end, and then the fireworks were kind of jarring.

General Help Q&A / Re: Reduced function set ML
« on: September 01, 2014, 12:22:16 AM »
It's not practical for them to do this IMO. ML has so many functions that appeal to different sorts of photographers and videographers. If they release a minimal version of ML with those 3 functions, some other photographer is going to want a minimal ML with another different set of functions. Best way to do this is to disable modules that you don't want

There is no ML histogram in Playback, so I don't know what you are taking about. Maybe you think the Canon histogram is from ML? Canon histograms are not based on raw data (again read the link)
I don't know about other cameras, but on my 60D, you can press unlock to get the ML overlay while in playback mode. I use it mainly for the peaking and the histogram. If I want to look at the Canon histogram, the image will be too small for me to see anything useful, so I prefer using the ML overlay

That's correct: in playback mode, ML only has access to the processed data, so it's not possible to produce a raw histogram, unlike in quick review mode, where the raw buffer is accessible.
Ah, that's what I couldn't figure out, thanks.

But this means that if I want to get as close as I can to a "raw histogram" in playback mode, I need to use picture styles to tweak the jpg preview.

EDIT: So I just tested Cinestyle and it is indeed the closest I get to a RAW histogram...In fact I can't tell the difference between the RAW histogram (from image review) and the jpg histogram (from playback)

Again, it's not called a raw exposure aid for nothing. Did you guys even read the link? Like, I don't know, maybe the first sentence.
Well I just did a quick test...I set 1 picture style to neutral, with max negative sharpness, contrast and saturation. Second picture style with standard, with max sharpness, contrast and saturation. Used auto ETTR, then shot 2 pictures in raw, alternating the picture style.

ML histogram in playback on first shot showed plenty of headroom to increase exposure, histogram in second pic showed that I had almost clipped highlights.

However, in quick review, the histograms seemed to be the same (both shots had plenty of headroom to push highlights)

For raw, you really shouldn't be judging exposure by "looks", you are only getting lied to. You should exclusively be using the raw exposure aids. What might be beneficial is if it were possible to craft some sort of picture style that rendered overexposure in raw the same as overexposure in YUV, that way you could use fast YUV zebras (raw zebras are slow and use the CPU, YUV zebras don't). IDK if something like that is even possible.
Using raw exposure aids is good for live view, but what about shooting photos through the viewfinder? The histogram (even the ML one) from the playback is based on the jpg preview, right? In such a case, the picture style affects the histogram because it affects the jpg preview. I currently use neutral with maximum minus sharpness, contrast and saturation

Unfortunately, ML raw exposure aids don't work through the viewfinder...It would be great to have the ETTR hint and raw histobars in the viewfinder, but unfortunately we don't have EVFs in our cameras :(

1. fixed
2. expected behavior (this is kind of separate from the bulb timer, but I put it in the same menu, maybe thats a little confusing. But I have no way of determining if the bulb timer is enabled from a module).

1. Thanks for fixing the incorrect half ev calculation
2. In that case, maybe it should have a separate menu entry?

11
I just did a quick test and noticed some weird behaviour

1. 10 stops and 10.5 stops seem to be swapped. When I set exposure to 1/30s, 10 stops reports 47s exposure and 10.5 stops reports 31s exposure. Haven't tested the rest of the stops
2. The trigger does not turn off when you turn off the bulb timer; it only turns off when you turn the bulb->ND feature in the bulb timer sub-menu

Tutorials and Creative Uses / Re: Save JPEG Files back to camera
« on: August 06, 2014, 05:14:19 AM »
you mean you want to copy someone else photo and make it seem to be shot from your camera?

even if you do not mean to be that way, this can lead to legal problems NO?
I think the TS just wants to copy the composition. I don't think the intention is to "change the EXIF info" to make it seem as if he/she shot the image. It can be a good way to learn about composition, if you really want to do it that way.

General Chat / Re: [Looking for advice] 35mm prime lens on APS-C
« on: August 02, 2014, 02:22:31 AM »
How about the optical distortion ? Because to get a "35mm" look on an APS-C I need a 24mm with EF mount. But 24mm applies a certain distortion to the image, would that disappear on a APS-C?
Any lens, regardless of the mount, when mounted on a crop factor body, will be affected by the crop factor. EF-S means it can only be mounted on crop frame bodies and not full frame. The focal length specification on the EF-S lens is not the 35mm equivalent.

14
I'm not sure if I should post this here or under feature requests, but here goes...

Can a "link to Canon shutter" like the one in the ETTR module be implemented? I'm not sure if it has been suggested before (in fact I might have even suggested it previously but forgotten about it)

Basically if you turn the main dial it changes your Tv minimum value to that value, and if you turn the rear dial it changes your max aperture in the Av range.

Feature Requests / Re: Long Exposure ETTR setting
« on: July 29, 2014, 03:36:10 AM »
The key thing is to ask a coder to tweak ETTR to provide exposures greater than 30(32) seconds.

Let's hope.
Maybe have ETTR link to bulb timer, and we do everything in bulb mode? I don't think it's possible to set exposure >30s (32s) in manual mode. With ML bulb timer, bulb mode is pretty much manual mode without 30s limit anyway

EDIT: I see a problem with this: exp sim and histogram/zebras etc. when in bulb mode

General Help Q&A / Re: Huge font size
« on: July 29, 2014, 03:32:48 AM »
I can't remember, but anyway I just solved it by deleting all the ML files on my card and copying all the files over from a nightly build

@brapodam

I understand fully what you are saying.

I'm suggesting that with ETTR we have another workflow.

Taking an ETTR reading is seconds.

To be clear, my ideal workflow would be as follows (based on having a fixed ND 'stack':
1. Compose & focus, of course;
2. Put on the filter(s) you have - for most of us having one or two is a luxury, ie we don't normally use the ND as a 'variable' in LE shooting (no pun intended wrt variable NDs);
3. Set ISO 100 and a mid aperture and get ML to estimate the LE shutter speed;
4. Adjust aperture and ISO to get a shuuter speed nearer to your artist desire, assuming you weren't lucky first time.

As I say, if ETTR could be enhanced to give us a shutter speed, for a given ISO and aperture, I believe it will greatly help with LE, as you wony need any apps!
Hmm, perhaps a ND calculator integrated with ETTR? Workflow will be as follows:
1. Go into live view, compose, focus and press set to activate ETTR
2. Go into ML menu, set ND filter stops and target shutter speed (maybe even have an exposure offset function to compensate for changing light or the ND filter blocking off more light than specified)
2a. The ML menu shows you the ISO and aperture settings required for the target shutter speed (this is just a calculator based on the current exposure settings, no metering required)
3. Go back to live view, double press half shutter to set exposure settings, put on ND filter

As I have mentioned before, I usually want a specific shutter speed, so I want to lock that first before I care about aperture or ISO. I also try to use the lowest ISO, so unless I still don't have enough light when I have my lens wide open, I won't raise the ISO.

I do long exposures quite frequently, but mostly during sunrise/sunset. This is a cool idea, but I see 2 potential problems

1. During sunrise/sunset times, the light conditions change too fast. By the time you screw on the ND filter, your exposure needs to change. I normally just ETTR before I put on the ND, then use a phone app to get the required shutter speed, and compensate for the change in light.
2. People who use a ND filter usually want a specific exposure time, not an automatic solution. I might want 30s to smooth out clouds, or 2s to have a nice wave formation. This is why I usually make sure that my exposure time before the ND filter is a specific one, then I'll compensate for the ND only with shutter speed (and ISO if required)

General Help Q&A / Huge font size
« on: July 28, 2014, 04:53:56 PM »
A while ago proportional fonts was implemented so we don't have huge fonts making the menus look ugly, and it worked great.

Today after I loaded in a nightly build I compiled, the font size became huge again. Any idea what is causing this weird behaviour? I've tried downloading a prebuilt nightly and using it, but fonts remained huge.

20
thnx Alex.  I will go refresh my reading on ETTR again.  If you have any recommendation for camera settings, it would be greatly appreciated
I guess if you're doing day to night or night to day, just shoot wide open and ETTR should take care of the ISO and shutter speed. I'm not sure about white balance though. I don't do time lapses, but I do occasionally experiment with it when there are developments in silent pics

21
Has anyone succeeded to get a fullres silent timelapse in MLV format using ETTR ?
Yes, I have succeeded in shooting a simple test while using ETTR. I haven't used mlvdump though. I used the MLV batch converter from this thread http://www.magiclantern.fm/forum/index.php?topic=10198.0

It worked without errors for me

General Help Q&A / Re: Dual Iso first try
« on: July 23, 2014, 02:45:21 AM »
Just done this for the first time (windows 8) and it didn't work - soon discovered the CR2 file needs to be in the same folder as the cr2hdr.exe file.

Dragging the image to the exe creates the .dng file in the same folder.

If you have them you can open in adobe camera raw by opening in photoshop OR open in Lightroom (works for me - though I've seen suggestions it doesn't).
I just use the cr2hdr plugin from this thread: http://www.magiclantern.fm/forum/index.php?topic=11056.0

Oh i see.Yes for the 60D i used the July 22 nghtly with the silent.mo you posted on post #153.So its ok to continue with 60D and July 22 nighly if i understand correctly?
I actually did the same with my 550D but with the silent.mo in mk11174 put in  latest 60D build only with full res silent pics (no mlv).
Should i stop using that as well?
I have no means to compile the build for the 60D you say though,if someone has already done that and wouldn't mind posting a link to it
i would continue shooting further tests or any kind of test you or anyone else would like for me to do.
I've used a self-compiled build from the main brach with dmilligan's silent.mo on my 60D without any problems, but I've compiled a build from his branch, and here's the link:
https://www.dropbox.com/s/yhevc9pkdkhuvsp/ML_60D.zip

Interestingly enough, I've had a weird bug with the build from his branch, but I think it's unrelated. After shooting a short test "time lapse", my camera refuses to take pictures, and the live view button has decided it would function as a AF mode toggle instead. A battery pull fixed the problem though.

24
Do you have the mlv_play and mlv_rec modules loaded too??? I think both have to also be loaded to make this link correct.
Ah, yes it works now

25
trying on my 5d2

tcc: error: undefined symbol 'mv_fill_wbal'
tcc: error: undefined symbol 'mv_fill_rtci'
[E] failed to link modules

What I did was take mk11174's
https://bitbucket.org/mk11174/magic-lantern/downloads/magiclantern-Nightly.2014Jul19.5D2212.zip

and swap out the silent.mo
Same error on my 60D, compiled from main branch and replaced silent.mo
