SamSteele Posted July 9, 2021 Share Posted July 9, 2021 Aff Photo 1.9.2.1035-Win 7 I have an H&S RGB portrait photo jpg file that was scanned and the scanner left slightly visible bars on the face and forehead. Pls see attached sample of cheek. Is there a quick way of removing them, or at least ameliorating them? If you sit way back from your screen they're visible.TIA.

h_d Posted July 10, 2021 Share Posted July 10, 2021 Hi @SamSteele You would probably get better answers if you uploaded the original image rather than a screen grab of a tiny part - if I sit way back from my screen it looks like a spectacularly unsuccessful bowel movement 🤧 You could select the offending area and try a Gaussian Blur. Or a Diffuse: But without sight of the original it's hard to tell. Cheers H Quote Affinity Photo 2.0.3, Affinity Designer 2.0.3, Affinity Publisher 2.0.3, Mac OSX 13, 2018 MacBook Pro 15" Intel.

Joachim_L Posted July 10, 2021 Share Posted July 10, 2021 @SamSteele Or install the G'MIC plugin, which has some good (and some not working) noise reduction / debanding filters. The one works best for is in the test category. A weak machine like mine takes a bit longer for filtering.

John Rostron Posted July 10, 2021 Share Posted July 10, 2021 Often the FFT filter will fix problems like this but, having tried it, I have found that it will not!

SamSteele Posted July 10, 2021 Author Share Posted July 10, 2021 I accomplished what I wanted (not perfect, but much better) by using a New Live Filter Layer >Blur > Median. 20 px; 68%; Average. Details in the eyes, etc were excluded. The selection brush is quite accurate once you get used to playing with the size keys [ ] . Way back in the day I could have retouched it using pencil on a 4x5 neg. (/brag) Quote Link to comment Share on other sites More sharing options...

NotMyFault Posted July 11, 2021 Share Posted July 11, 2021 (edited) Taking a different road to a more targeted approach: use frequency separation with 3px to isolate unwanted color issue add B/W adjustment. Set blend mode to difference merge visible (looks almost black but isn’t, use levels adjustment to better see ) hide helping layers Set blend mode to add adjust opacity to about 30% gives optimal result This preserves the fine structures. you may need to experiment a bit with px settings. BTW the HF layer shows that a low quality jpeg compression amplified the scan damage.
