I shot a model posing to show off a dress. She wore grey shorts under the skirt of the dress, which was red with white spots on. It should not have shown so I now have a picture which shows a patch of grey where only her leg should have been. I need to clone the shorts out.
I vaguely remember doing something similar in darktable a while ago but now I can’t remember how nor can I find the relevant section or module in the manual to do the job.
I could do it in the GIMP but that wouldn’t show in the DT history, which I’d prefer to have in case of future editing from raw.
