2.3 stable doesn't work on 1100D.

The nightlies are more stable than RC3 actually, that's why I crossed it out ;)

No,only timelaps play is working

When you're talking about "set+wheel", is it about a special feature or just navigation through menus and item selection ?

It's exposure fusion in play / review mode.

Okay, so I can't say it work, but don't know how to test it. Can't find how to test the exposure fusion.

- I tried activating "Anamorphic preview"  to 2:1, and now the display blink and show black images (can do a video if you need it)
- RGB zebras in live view : activated it, but nothing's displayed

Uhm, anamorphic preview -> Should squeeze the image veritcally in liveview (so half black, half image).

Exposure fusion:
Take a couple of  pictures of the same scene with different exposures,
Open ML menu, go to prefs, Image review settings, SET+MainDial -> Exposure fusion (try compare images too).
Go into "Play mode", select the first of the HDR images, hold SET and turn the top wheel

- In anamorphic preview, half image black (top), but the displayed part isn't clean, like if it is lagging. And at the bottom of the screen there's a noisy pink bar made of dots.

- Expo fusion is working, but whan 'computing' the image or something like that, some small black bars appeared at the bottom of screen for a few second. When I turn the wheel, there's an overlay with '9 images' in the top left corner.

- Compare image is working too, but the top bar hide a part of the image

Hi Nanomad,

The issue that kapueblo had with the changing exposurestuff sometimes happens to me as well when i point at a bright light source. But in my case i can see the aperture blades moving. Does this help you any further?

Cheers!

Mediocre45

This still only happens with my kitlens by the way

nanomad

In what mode? Movie? or Photo? Do you have exposure override or exposure lock enabled?

In the movie mode. Yes to exposure override, no to exposure lock

nanomad

Try enabling shutter lock (not exposure lock, my bad) and disable gradual expo or fps override if they are ON

I did like you suggested, enabled shutter lock and made sure gradual exposure and fps override were disabled, but still happens.
To further clarify; It's not something that always happens, but when it does my aperture is set to high f stops like around f16 to f22 and it also usually happens when i'm trying to film something light in a dark room. If i try to film my monitor at night for instance. This also only happens with my kit lens, so it could be just something with the lens that is off or something :p

nanomad

Could be, the manual exposure in movie mode is an unexpected result thanks to the 600D and 1100D sharing the same hardware ;)

Good night. I have a problem, I have nightly 18/10/2012. In video mode manually, when I change the aperture value, exposure of the image changes little or nothing, but the value f / changing. Exp override: ON - Sutter Lock: OFF - Gradual Expo.: OFF

Thank you.

nanomad

This is one kind of issue that I've not been able to debug properly since it works fine on my camera....
Try clearing camera and ML settings and try again  :-\

Manual exposure in 1100D seems to be actually sort of a debugging feature.

Nanomad: can you hexdump LVAE_STRUCT? Maybe it's some offset that we need to change, and we don't know about it.


nanomad

Actually, there are two functions called
EP_SetManualExposureMode @ 0xFF28A3F8
that sets
*(LVAE_STRUCT + 0x74) = 1 -> Manual Expo ON
*(LVAE_STRUCT + 0x74) = 0 -> Manual Expo OFF

and
EP_SetMovieManualExposureMode @ 0xFF28A2C4
that sets
*(LVAE_STRUCT + 0x78) = 1 -> Manual MOVIE Expo ON
*(LVAE_STRUCT + 0x78) = 0 -> Manual MOVIE Expo OFF

Try them, look in update_lvae_for_autoiso_n_displaygain for hints about what they do. I was able to limit minimum auto ISO in movie mode with this trick, but not the maximum one.

nanomad

To anyone having issues with exposure in movie mode, try this autoexec.bin and report back please
http://nanomad.magiclantern.fm/1100D/autoexec.bin

(I'm calling "lvae_setmoviemanualcontrol" in addition to "lvae_setcontrolbv")
