I spent half an hour on it at work today (don’t let my boss know;).

 

It’s easy enough to clean up; the hard part is re-introducing colour back into the right side of the image. Especially your arm and hand. I'll keep at it. I could do with some practice for sure.

 

Quick and nasty  tip: I started out with Noise/Dust and Scratches filter with very low settings. Then unsharp mask filter; it loses a bit of sharpness when you use dust and scratches. This got rid of a lot of the hard work quite easily.

 

Cheers hawfyr!

I never intended to make art.
