Hi, I'm having issues with a checkerboard/moire pattern in dark areas of my photos. I shoot with a Leica Q2 monochrome and in camera raw the file looks fine but when I open it in PS(latest version) on a Mac M1 you see it and if I convert the image to RGB to use with Nik software the pattern gets worse. The pattern looks like a pincushion but reversed. This just statrted when I updated to the latest version of PS. Any ideas. Thanks Ed
Could you show us the pattern with a screenshot?
What zoom level in Photoshop are you seeing the pattern? Can you see it when the zoom level is set to 100%?
What are your settings in this preferences pane?
I can see the pattern in your attached screenshot, but does it disappear if you view your original image at 100% zoom? That zoom level maps 1 image pixel to 1 screen pixel and is the only zoom level that shows accurately what is in your image, as opposed to other zoom levels which integrate multiple image pixels onto screen pixels and can therefore introduce artefacts.
Yes I see the pattern at 100%. There are several photos from the same location of image capture that this pattern appears. I've looked at other photos that I shot previously with this camera and do not have an issue. I'm thinking that the files could be corrupted but I also shot other photos this same day and don't have any issues. That image iso is 40,000 and others range from 40,000 to 100,000. All have that pattern. I've shot at these isos before and have never had any issues. So don't know if it's just a freak accindent or something with the latest version of photoshop. Sony sd card which I've also used the entire time I've shot with this camera.
