@Hangman Thanks for the welcome and the quick reply. I have done what you have suggested and the lines no longer appear on this particular image after sharpening using High Pass. We will see what happens to further edits. Thanks again

I use AP to 'process' my film scans. When I use the high pass filter I now get artifacts on the file. This has started happening after the latest update (2.04) and does not occur in AP1. I attach a pic to illustrate. I am running Mac OS Ventura on an M1 Mac Mini.
