Description

Hi.

I think Darktable should have something like LR's auto-stacking feature: http://www.tipsquirrel.com/automatically-stack-lightroom-images/

When i want to bracket shots i set my camera to burst and when i press the shutter button i get a set of closely shot photos. When i import those photos into Darktable i want to group those photos together. Darktable should have an option to auto group photos who's shooting time interval is shorter than a user-defined value, for example, 1 sec. This is only one possible use-case.

interesting... Once grouping is introduced in lua, it will be possible to do it that way...

Once exiv2 will fix Exif.CanonSi.Sequence, i'll implement something about this. (but the grouping will not be based on shooting time)

quick comment : lua now supports manipulating groups and group leaders. It can also read the exif date.

Some more exif fields might be added, but over all, I think this can be closed as "can be implemented in lua"

Grouping based on shooting time - yes.
Automatic grouping [on import] of images taken in a continuous burst - i do not think lua is needed here; it is going to be even simpler than JPG+RAW grouping.
Relevant exiv2 bug

there is a generic question about DT that should be answered here...

should DT group images at import time, and (if yes) how.

We originally answered "regroup RAW+jpg" when the feature was implemented but there was no lua support at the time. My answer, nowdays, would be that auto-grouping should be a pure lua thing because it is very use-case dependant and we don't want to clutter the UI.

Ack, and it would also make the core code cleaner.
