[digiKam-users] Non-destructive editing in digiKam

[Taras]

Hi!

Consider following steps for edit original RAW file:
1. Open original RAW file for edit. Make some changes and press "Save to the current version". Now we have new image file (e.g. JPG one) for this version
2. Want to make new improvements and open for edit this version JPG file. Make some changes and press "Save to the current version".
3. Same N iterations

What file will be using as base for edit in step 2? The original RAW file with all history stack till this step or the previous version JPG file?

The jpg file you opened. Afaik, there is no way to reuse the history stack
from a previous edit.

Which might be a reason to save intermediate images in a non-destructive
(preferably 16 bit/channel) format.
