I have been processing a bunch of scanned photos where the photo is surrounded by the white background from the scanner. To remove the white background I use the Crop tool but I find this quite tedious because when I zoom in such that I can see the whole photo making it easy to access all four sides, it is very difficult to crop with pixel-precision. If I zoom in a lot then I cannot see the whole edge at once and I end up spending a lot of time moving around the photo. I have used the AutoCrop feature but it is not accurate enough and I still need to go through the manual process on several edges.
Improvement idea: Provide an option that the part of the crop outline where I click acts as a magnifier, so I can locate the crop outline with pixel-precision while using a zoom factor that leaves the whole photo visible. Benefit: time savings.
I am using PS 2022, up to date (23.1.1), on Windows 11.
