I have been working on reducing reflection noise in several scans. All the white dots are due to reflection from the scanner's light, due to glossy oil paint being used and the canvas curvature.
Have I pushed it as far as it can go, or is better possible? (Without blurriness/blotchyness/etc.) I'm not yet happy with the results. Re-scanning or photographing is not possible.
Some areas are decent, but especially in the dark areas (around the yellow, and edge of the flower) have too light of specs still.
This is a small piece of one image, and there are many images. I need to find a way to do this without doing a ton of manual work. I certainly don't mind having to spend a bit of time on each image, but manually doing the entire 16,000x12,000 file and the others would take forever. Also, having to manually mask areas would take too much time.
The original piece was on canvas, however didn't have the amount of variation in my "After" image due to the canvas -- that's still due to the original reflection noise.
Is there a way to get a selection from detecting noise, and use a content-aware fill across the entire image, based on its surroundings? I'm finding the noise tools aren't working well for me. I've tried several third party de-noise programs as well.
EDIT: Don't mind having to get a third party program, doesn't have to be Photoshop or Lightroom.
