General Chat / "Les Numeriques" covers Magic Lantern
« on: May 27, 2019, 09:45:12 PM »
... and because Je ne parle pas français I have no idea if they are doing it well.

Just curious ...
https://www.venuslens.net/product/laowa-100mm-f-2-8-2x-macro-apo/
This lens is available for Canon, Nikon and Sony FE. What puzzles me profoundly:

Aperture Blades    9 (Canon), 7 (Nikon), 13 (Sony FE)
Never heard of aperture blades depending on lens mount before! Any insight would be appreciated!

Few moments ago "Recently updated topics" looked like this:


Now it looks like this:


Given the spam induces validation period (which may take days) this will lead to new member's questions slipping under the radar and likely left unanswered.
Any reason why time frame for Recently updated topics has been changed?

If you are among those Firefox users and wondering what happened to your precious add-on collection (NoScript, Ghostery and several others): Bug in Firefox, certification issue. Official bugfix on it's way.
If you are one of those more paranoid users who disabled Mozilla's data collection option: Type about:studies as address and change your preference (top option in privacy). You will get a hotfix visible in about:studies soon after. I had to restart Firefox several times to get my add-ons back.
I'm an ESR user and unable to use bug-fixed nightly. After official bug-fixed release you may want to reset your privacy settings ...

General Chat / Advice on Drone?
« on: April 15, 2019, 11:49:30 PM »
Hi!

I will visit South America by motorbike. 5 months, I think. I want to keep my photo gear light. Just travel tripod, 100D/SL1 and some "plastic" lenses (EF-S 10-18, EF-S 18-55, maybe an 18-135 USM). Landscape, panos, some architecture, mostly. Thinking about adding a (small) drone to this. Does not have to carry a 100D! And no intention to accompany the bike while driving. But:
- 1080p video + higher res stills, if available. RAW for stills, please!
- must do have some high altitude abilities

No experience with drones, yet. And no unlimited budget.

Hello!

Created a flowchart about what is going on *before* running ML. I think it covers most what might be described as bootload stuff.
https://wiki.magiclantern.fm/_media/ml-prestartup_draft2.png

1): @a1ex: Roughly correct or not?
2): @all: Edible or unable to swallow?

And another one for a1ex: After wake-up from sleep there is another card check slowing down wake-up. What is the cam actually doing? Again checking for bootable card or just reading Autoexec.bin and other files?

EDIT: Dang! Forgot "Check if card is bootable!" New version online.

8
Curiosity, again:
ML default option for formating memory cards is "Format card, keep ML". I suppose (IANAP) ML works like this:
Copy files Autoexec.bin and ML-SETUP.FIR and all ML dir contents (*.*) to an allocated memory space, format card using Canon's firmware routines and restore files and directory from RAM to card.
Somehow correct?
If so: Is there an upper limit for number of files that can be stored and/or is there an upper size limit for single files or all files combined? I suppose it might be somehow camera dependent. Numbers available?

I suppose if I do something stupid like storing oversized video tutorials into ML directory it will break the routine resulting in - at least - corrupted and missing files after format.

General Chat / BoingBoing about Magic Lantern ... brace for impact ...
« on: February 20, 2019, 10:51:22 AM »
https://boingboing.net/2019/02/20/alt-firmware.html content found at O'Reilly (couldn't find anything there).
Boy, they managed to get most of it wrong!
1) ML does not replace Canon's OS. It runs along with it and Canon menus and actions are accessible, too.
2) It runs not only from SD but all flash cards you can insert (apart from SD-to-CF adapters which are crap and not supported)
3) The audio options described are for Digic 4 cams only (minus 50D, 1100D)
4) Oh, they actually got something right ... white-balance, exposure presets, overlays and open source.

Wait, haven't we been here before? Déjà-vu big time ...

Apart from this ... Anyone attracted by BoingBoing, please read before asking:
- No, ML does not run on recent Canon cams running Digic 6, 7 or 8 processors
- No, we can't say when it's ready. We have no clue, no release date or schedule to follow.
- Yes, we know you want it! So do we: Supporting not by offering money (we will ask if necessary) but by offering your coding skills (optimum: C and assembler for embedded devices, preferable ARM architecture), your time for testing code and nightly builds and experimental builds. Or go through our rather rudimental camera help proposal for errors and enhancements (link in signature).

Manually created Config Presets will appear in order of folders time-stamp.
I suggest to change order based on leading character according to alphabet.

In its present state handling of such entries is counterintuitive.

Feature Requests / Menu clean-up/redo: Liveview status "RAW" green -> white
« on: February 18, 2019, 07:35:59 PM »
Years ago there was a major redo in LiveView leading to a design with as few distractions as possible. Transistion from rather colourful status bars to black-and-white.

According to this design guideline I suggest to change "RAW" from green to white. I see no purpose keeping it in that colour.

I need confirmation for a strange bug in Expo. Override function. No hazard involved.
You need an rather old-fashioned lens like 50/1.8 I or II, EF 100/2.8 Macro and a newer one. Any STM should do and so does EF 100/2.8 L IS Macro. Don't know about other lenses fitting the scheme.
Any more recent nightly build would do fine and it doesn't matter if Digic 4 or Digic 5 cam involved.

Steps to reproduce:

- Preparation: Restore ML defaults (you may backup your ML/Settings dir to restore custom settings after test) and shutdown cam. Set lens to MF.

1) Testing "old" lens
- Remove battery, insert battery and powerup cam in photo mode.
- In Canon's QC menu set aperture to lowest number (wide open).
- Open ML menu and access Expo tab. Turn off ExpSim and turn Expo. Override ON.
- Enter LiveView. You may change shutter and ISO to get a proper view in LV. Do NOT change aperture! If you have accidently changed aperture -> Begin from 1) again.
- Press Trashcan button to access ML menu
- Highlight "Aperture" menu item and press set -> You are in Liveview again and "Aperture" menu item is visible in LV.
- Now turn top wheel one notch contra-clockwise. You should see number in "Aperture" changing to highest number available for this lens. And screen goes dark immediately after turning wheel.
- Check aperture blades. They should be properly adjusted to chosen aperture. (If unsure: Leave LV and use DOF preview button to compare).

(You can play around with top wheel if you want. Should do fine. Report if not!)

- Restore ML defaults, shutdown cam and remove battery.

2) Test "new" lens designs.
- Mount lens and insert battery.
- In Canon's QC menu set aperture to lowest number (wide open).
- Open ML menu and access Expo tab. Turn off ExpSim and turn Expo. Override ON.
- Enter LiveView. You may change shutter and ISO to get a proper view in LV. Do NOT change aperture! If you have accidently changed aperture -> Begin from 2 again.
- Press Trashcan button to access ML menu
- Highlight "Aperture" menu item and press set -> You are in Liveview again and "Aperture" menu item is visible in LV.
- Now turn top wheel one notch contra-clockwise. You should see number in "Aperture" changing to highest number available for this lens.

- Now things won't work the way you expect. I think you may see some laggish response or even none after turning the wheel. Try turning wheel until screen goes darker. Maybe you have to force it by half-pressing shutter button (not sure about this one).
After screen goes darker check aperture blades position. You may observe they are not as closed as they should be! You may cross check leaving liveview and using DOF preview button.

Please report back with
- cam used
- lenses used

And don't forget to remove your battery after 2) completed. Menu may behave strange, too. And camera shutdown by power  button is only optional, I suppose. ;-)

Thanks for your time!

Feature Requests / Adv_int.mo: Loop After, easier edit function
« on: February 15, 2019, 03:13:14 PM »
Only way to change number is incrementing/decrementing by button press or wheel. Would be appreciated if working like "Stop after" where you can select and change each digit.

At the moment there are two modules (pic_view, mlv_play) adding features into file manager. And not able to do much without.*
What is the developers pick on that?
Does it make sense to merge these functions into file manager or do you prefer to keep them seperate for easier development (or other reasons I'm not aware of)?

*MLV_Play enables playback of last record from RAW menu *without* file manager.

15
Steps to reproduce:
Start photo mode with ML defaults.
Take a pic.
Switch cam to bulb mode.
Open ML menu. Go to Shoot screen -> Bulb mode -> Q
Set Exposure duration to 40 seconds
Set Display during exposure to Show previous pic
Leave menu by half-shutter press.
Press half-shutter for > 1 seconds. Cam should make a beep and beginn to take a pic.

Expected result (with bug):
- Screen turns dark (no pic shown) and remaining time counts down. (Upper left area).

After bulb mode terminated you will see the pic in review.

Now take a second pic in bulb mode. Expected result (with bug):
- Screen turns dark (no pic shown) and remaining time does not show up at all.


Please test (owners of other D4 cams as well) and report back!

EDIT: Found time to downgrade to 2.0.3 and build #3 (2013Dec22). Did not work either. Third shot with option Show previous pic: No countdown line written. And clock (counting up exposure time, showing lower right corner) doesn't show up at all. Missing pic, too.
More to debug:
Option "Display during exposure Don't change" doesn't show any message. 650D shows clock incrementing.
Awaiting reports from other D4 owners before opening Bitbucket issue.


650D, option "Display during exposure Don't change"

Not sure if here or Tutorials and Creative Uses is the right place to ask.

Came up with an idea for future tutorials. I think users might want to have some kind of reference for the things written to Quick Control screen by ML. Could be in written/non-interactive form with pics like this (incomplete):

or interactive for electronic devices (no example here).

Question 1: I looked into source code trying to find out which features are interacting with Quick Control. But I suck as a programmer and couldn't make sense out of it. Is there a list of features writing to QC screen?

Question 2: There a some differences in QC screen between my 650D (Digic 5) and 7D (Digic4).
QC 7D

Examples:            7D        650D
Battery level:       yellow    none
MLU:                   yellow    white
Adv. Bracket         none     white
intermediate ISO  alligned not alligned/artifacts
Date                    none     white

No lens info, no build info displayed in 7D's screen.
May a developer drop a word about those differences? Has to work this way because of Canon or something lost/gained in transistion? I kind of like ML's interaction highlighted. Personal issue, of course.

And another one:
AFAIK option "LCDsensor Remote" is the only one where menu icon changes this way. I think it is redundant and should be dropped to maintain user interface standard.

As discussed in https://www.magiclantern.fm/forum/index.php?topic=3511.msg18078#msg18078
"Steady hands" feature outside liveview is unreliable.

Request: Force cam into liveview if enabled. It should work the same way "Expo. Change" and "Frame diff." do: Press half-shutter and liveview it is.

18
There are 2 menu items in Shoot -> Shoot preferences: "Post scripts" and "Intervalometer Script".
Post scripts are optional used/generated by Adv. Bracketing and Focus stacking.
Intervalometer Script solely by "Intervalometer".

Q: Is it possible to move these items where they are used?
- Create double menu entry "Post scripts" in "Focus" -> Focus Stacking" and "Shoot -> Adv. Bracketing". Yes, same function, 2 menu entries.
- Menu item "Intervalometer script" moved to "Shoot -> Intervalometer". I think renaming to something like "Helper script" should be done because it is obvious we're in Intervalometer.

EDIT: I have no problems with "global" settings "Snap Simulation" and "Pics at once" placed in "Shoot Preferences". I just don't like features linked to specific options here (even if they affect 2 or more features). Makes no sense for me to leave menu for a feature (Intervalometer, Focus Stacking, Adv. Bracketing ... to name some) and move here to a) make sure I have the proper setting and b) to adjust it to my need.
And yes, if you're suspecting I'm gonna ask for "Use Autofocus" to be moved/spread, too.

Hello!

I humour myself using search strings "Magic Lantern Canon" in Google restricting search results to "Last 24 hours" from time to time. Useful to find new stuff related to ML ... once. The last days it seem Google has fallen for SEO of the bad kind: Pages filled with thousands of search strings comes up first and it goes on and on. Okay, for users able to interpret nonsensical strings like "www.blabla.wherethebadboysare/kajdfjaerfk/slakdfjljef/m=sadf/..." without clicking them its just annoying. For other users going to find information about ML it is almost impossible to get linked to ML home and forum page.
Disclaimer: I'm not a web master.
Q: Is there something the web admins can/should do about it?

EDIT: Search strings like "Magic Lantern" without restrictions work just fine.

General Development Discussion / Q on LV Display Presets (@a1ex?)
« on: January 16, 2019, 03:39:02 PM »
Curiosity again:
Settings for each display (numbered 0-3) are stored in MAGIC.CFG in lines disp.mode.a, disp.mode.b, disp.mode.c and disp.mode.x into a number. Decimal number interpreted as binary where each bit represents a setting (or combined bits for items with more than 2 options). Right?

General Development Discussion / Dual-axis electronic level: Status?
« on: January 04, 2019, 06:53:17 PM »
I tried to lookup for this topic but found nothing: Some ML enabled cameras are equipped with dual-axis electronic level but ML only supports single-axis level indicator (7D, at least). Anybody tried to make it run?
Low priority, just asking out of curiosity.

London, UK, Wednesday 2nd January 2019 — Canon Europe, a world leader in digital imaging solutions, announces the release of its new camera API package, offering a range of resources to developers. The combined EOS Digital software development kit (SDK) and all-new Camera Control API (CCAPI) create unique opportunities for developers and software engineers to take advantage of select Canon cameras and lenses, launching with the PowerShot SX70 HS.

Power your enterprising vision with Canon PowerShot SX70 HS, the first product supported in 2019

Powershot_SX70_HS.jpg

Many developers have already benefited from Canon SDKs, enabling them to integrate Canon cameras and lenses in their solutions and control them remotely, wired via USB. Such applications include photo booths, robotic / automated units, event photography and recording, mass portrait / passport and photogrammetry systems.

The EDSDK benefits will allow users to control Canon cameras remotely from a Mac or PC and use the same code across all compatible Canon cameras. To take advantage of multi-platform support on select models1 for fast development, the new CCAPI features an agnostic operating system, allowing wireless usage in any environment, such as Windows, Mac, Android, iOS or Linux.

Key EDSDK/CCAPI functions include:

    Detecting, connecting/disconnecting the camera
    Checking and changing camera settings, including time
    Remote shooting
    Downloading/erasing images, formatting cards

“We are delighted to be expanding our EOS Digital SDK to the PowerShot series2 and provide a tool that enables control of the camera and its power zoom remotely”, said Yuko Tanaka, ITCG Product Marketing Director. “In addition, the new Camera Control API is based on Internet Protocol, making it compatible with all operating systems”.

The PowerShot SX70 HS is Canon latest premium bridge camera, that delivers a truly portable and versatile shooting experience. The camera features a powerful 65x optical fixed lens zoom, equivalent to a 21–1365mm focal length. It also has DSLR-style looks and handling, a 7.5cm Vari-Angle LCD screen, 20.3 Megapixel sensor and 4K Ultra High Definition video. The PowerShot SX70 HS is an ideal all-in-one camera, capable of handling all types of shooting scenario, without the need to carry multiple lenses.

Camera API Package Availability

The camera API package is a release driven by business users’ feedback and is part of Canon’s commitment to deliver convenient solutions to developers and integrators. The EOS Digital SDK is available for immediate download at www.didp.canon-europa.com.

The Camera Control API will be available from March 2019 via the Canon developer’s website.

Feature Requests / Menu clean-up/redo: Audio tab displayed all the time
« on: January 03, 2019, 05:54:09 PM »
Another itch (and FAQ): Audio tab for non-D4 cams is visible after enabling mlv_snd only. IMO it would be preferable to have Audio tab visible all the time. For those cams not supported by ML audio features (including 50D) there should be a notice why there are no/shadowed menu items. Link to feature list, too.

24
There are at least 3 menu items affecting overlay status :
Overlay tab -> "Global Draw" with options "OFF", "LiveView", "QuickReview", "ON", all modes".
Display tab -> "Clear overlays" with options "OFF, "HalfShutter", "WhenIdle", "Always", "Recording".
mlv_rec.mo -> Movie tab -> RAW video (MLV) -> Global Draw" with options "OFF" and "Allow".

I find this to be counterintuitive and it's making tutorials/help texts messy.
Any chance streamlining this?
