The download and renamed of pictures from camera take a set of unsort photos. The order of the list of pictures is different at the order in camera. This is a uncomfortable problem for the focus stacking technique or HDR, and this prevents I can to use digikam if I take a timelapse.
Please updated to last 2.5.0 where a lots of sorting options have been added... Gilles Caulier
This problem is not reproducible using current 5.8.0 pre-release bundle available here : https://files.kde.org/digikam/ I close this file now. Re-open it if necessary. Gilles Caulier
