Problem with file not reponding to Photoshop Adjustments ie Levels
I have a jpg that does not respond to adjustments. For example if I lighten the file using Levels, the effect shows up while adjusting but when I hit OK it reverts back to being dark with only about a 5% change. It's like a dark film is laid on top of it. It is a scan from a printed book so it is dots. I've tried copying, different formats etc but it acts the same way.
Help! and thanks.
