I've searched the wiki, and found "quite a lot" of exposure bracketing programs.
There is tremendous variation in what feature they need from CHDK (esp w.r.t props), and how they work.
IMHO the ones that use EV compensation are not usable. Any "proper" HDR bracketer should take (at most) one meter reading, and then work by altering shutter speed. Altering aperture is not good, since it would give different depth of field on the shots, altering the image itself.
The better scripts use focus lock, to avoid any focusing time after the first shot.
The better scripts put the camera's setting back to how they were at the start of the braketing run.
Scavenging...
This one does shutter speed bracketing (but no other good features)
UBASIC/Scripts/CanonA640: Shutter Bracketing - CHDK WikiThis one exploits focus lock:
UBASIC/Scripts: an ultra fast HDR bracketing script for A6xx - CHDK WikiThis one uses a half clock to get back to start point:
UBASIC/Scripts: EV bracketing with TV and AV commands - CHDK WikiI'm also fuzzy (but willing to learn) about the various CHDK builds that are mentioned; are these divergent builds mainly for the developers, or does each build have a sub user-group?
I'd have thought HDR would be quite a prime target for this group, but I can't find a good script for it.
Can anyone help me?
