Vidi Posted February 9, 2021 Share Posted February 9, 2021 Hi I am troubled with Scanlines in my Scans of Old Photos. Scanning them with 1200 dpi. And just for Print or Displaying they are good enough. But as soon as i work with them (like sharpening) Scanlines become visible. Now to my Problem. It only happens in certain Areas of wihte and grey. So using "FFT Denoise" works but i get Banding on other Areas. Zoomed in With "Detect Horizontal Edges" i can make the worst parts visible. Zoomed in But how do i proceed from here out on to only use the Filter on this Areas in the Final Picture? And is there another Option than the FFT Denois Filter. Because i have a couple of hundred of Pictures and FTT does not work in combination with the Macro Feature for Batch processing. Hope someone got an Idea Quote Link to comment Share on other sites More sharing options...
carl123 Posted February 9, 2021 Share Posted February 9, 2021 I think you need to upload a full size image with the problem "Scanlines". We cant do/see much with what you have uploaded so far.

Vidi Posted February 9, 2021 Author Share Posted February 9, 2021 If you look around the mouth or the left ear (zoom) it's good to see. Espacilly if you apply sharpening. Quote Link to comment Share on other sites More sharing options...

firstdefence Posted February 9, 2021 Share Posted February 9, 2021 I came up with this method. Duplicate the background layer Set the blend mode to Average Adjust the size of the image on the Average blend mode layer from the centre node from 4004px to 4014px Before After Quote iMac 27" 2019 Sequoia 15.0 (24A335), iMac 27" Affinity Designer, Photo & Publisher V1 & V2, Adobe, Inkscape, Vectorstyler, Blender, C4D, Sketchup + more...
