Yea i know but without the original file there’s nothing you can do to remove what you’ve added. I’m not sure you can go thru the History in photoshop and delete what was done unless you have a psd file.

If the original file has been lost then to be honest, the image may as well just be written off rather than mess around trying to ‘unsharp’ it. There comes a point where you process an image so much that anything else will just make it look worse rather than better, and that is what I think Grey Area is getting at. Less processing always produces better images. Always!
