I'm resizing photos uploaded to a photography gallery and have thus applied an unsharp mask to attempt to preserve the photos original sharpness. The settings I use are:
radius: 0 sigma: 0.5 amount: 1 threshold: 0.05
I have noticed in some cases that photos are appearing over sharpened. Particularly when photos have high contrast close together lines.
So, what are the best settings for the unsharp mask after resizing? something I can apply to any photo uploaded and get the highest % of correctness. I understand that occasionally one won't look correct.
