I have this picture from Mexican PB that I'm going to merge but as you can see the right side of the picture is much greener than the left. This is not a scanning error. It was printed this way.
I use Photoshop Elements 9 as my graphics program. So far I've tried changing the tint, temperature, adjust color for skin tone, and a number of other adjustments. Nothing comes close to fixing the problem. In the picture between the heads of the 2 models the background is brown on one side and green on the other. Is there some way of making the right side of the picture more brown?
