I think I'm liking my new method for enhancing very weathered petroglyphs. I'm using the combination drawn and parametric masks in a second Darktable exposure module instance. First I paint in where I want the mask. Then I adjust it using the parametric functions. Then I lighten the faded petoglyphs. What do you think? Does this image look too manipulated or does it look fairly natural?
@elaterite Looks rather natural to me!
