Some relatives mailed me this photo. It’s a one and only smartphone shot from a rainy hike in Iceland. The photo is badly damaged by water on the lens.
Could I do some magic with Darktable to recover the photo?
Below you will find my result. I used a lot of local contrast in combination with masks.
Can anyone do a better job? And how can you recover the “bleeding” of the colors around the yellow hat and the blue backpack? I used spot removal to copy other parts of the background to repair the bleeding. Maybe the channel mixer could do a better job?
