Quote from: reyalp on 31 / October / 2010, 00:22:23One of the ideas I've had along these lines is to automatically capture a RAW/DNG if the histogram shows lots of dynamic range in the scene.You could do this in script with shot_histogram I think, but it means you have to use script for shooting all the time.Quoteps - almost forgot - it would also be nice to "lock" an exposure/focus point ( half-pressed shutter ) without holding the shutter button down - and then adjust the zebra pattern via EV, Tv, Av, etc. That would be too good! Maybe someone already achieved something like this.Canons firmware already has AE and AF lock on many models, check your manual.The problem with this suggestion is that exposure lock on my Ixus 95 is the same button which is used for changing Ev- half shutter/top button. Trying to change exposure turns AE lock off. I think that the original idea for an improved zebra remains a good one. If anyone wants to code something I am happy to test it.

yes, display zebra just like the histogram can be displayed- on all the time so that Ev adjustments can be seen working, as they are madeI think that "lock" did not really mean lock, but meant continuous display (of zebra)Colin

Somehow, the code only displays zebra when half shoot. Easy modification to fix. However, it is not my piece of code I do not feel entitled to mess with it unless for my own personal use.Toine. PS: I'll let you know how it works with my A610. What's your camera?Other though - so far we have over exposed zebra. We'll also need under exposed zebra so that you can adjust until some portion of the picture become too dark. This will give you the bracket range.
