After thinking about that I came to the conclusion that this would be best done with Lua. Everyone has their own (albeit similar) wishes there so a set of a few Lua scripts (or one with a few config switches) would be the best way to go. Currently darktable allows to register a callback that is run after an import, so it would already be possible to remove images from the db that are not wanted. However, that would still waste a lot of time since these images get imported first, might get a sidecar file and maybe even a thumbnail created. To make this more useful we are currently discussing the idea of a list filter for import and also export that could remove (or add) images to the list of to-be imported/exported images. This won't land in the 1.6 series though, so if anyone feels bored, a script that removes unwanted files from the imported film would be worthwhile for the time being. To get you started, the important callback is post-import-film (http://darktable.org/redmine/projects/darktable/wiki/LuaAPI#post-import-film). > Best regards > > Chris Tobias
