Does anybody know what is the best way to batch process ~400 pictures with different exposures? I had to change the exposure accordingly to light conditions. But then I’m struggling to process all those pictures together because first pictures are slightly overexposed compare to last ones. Do you have any idea how to set, either RT or Darktable,
Darktable 2.0’s auto-exposure mode is supposed to do that. It’s based on Magic Lantern’s deflicker module.
If you want to do some automatic things, open the folder I’m the RT file browser, then select the auto exposure and any other desired parameters from any tools, then Ctrl+b to send them to the batch queue, and then start the batch queue from the batch tab.
I don’t think Auto-Levels will give you the kind of results which would be usable in a time-lapse, but there was a project called DeSERt, renamed to Lapse-Studio, which uses RawTherapee for exactly this kind of thing. It’s not actively maintained, but might still work.

Or try this per script:
Thanks a million. I know about cyberangl3l deflicker and I use it but it wouldn’t work in this case. This deflickering script is great when there’s only a few pictures with different exposure and the rest is pretty constant but the exposure of my pictures changes, let’s say every 50 pics… and therefore auto-levels is actually better tool even though I cannot play with the exposure itself that much but for final results it’s just fine and is much smoother! Thx again.
