I'm trying to add "EC on M" to the auto iso module - so far so good, it's basically adding/substracting some shutter or aperture and setting it (thanks for figuring out round_shutter...), respecting some limits. Problem is:
If I modify aperture/shutter in M mode, it immediately shows as if the user would have set it and doesn't work as ec in tv/av. So I have to correct the exposure value before and after taking the shot. Is there a way to "wrap" the Canon shot with ml functions, i.e. hook before and after it? If not, I'd have to try half shutter as before and somehow shoot task as after, but I don't think I'd get this to be really reliable :-\
Before: no, other than polling half-shutter. You could dig into the state objects, but you can't change settings from there (well, I couldn't).
After: for ETTR I use the quickreview mode.

Thanks, I'll use your method then, now I understand why you did it like that :-o
