Using Sharpen AI Trial. If I launch it as standalone app, it works as it should. If I’m in Lrc, right click, edit in > Sharpen AI, the app will process the photo terribly. The noise increases and doesn’t sharpen at all.
What type of image are you processing, try a TIFF with LR edits applied.
It’s a .CR3 that’s converted to TIFF when sending to Sharpen AI via Lrc plugin. I tried sharpening the TIFF by loading it in Sharpen AI stand-alone and it wouldn’t sharpen or process the TIFF at all. If anything, it becomes worse.
