Chromatic Abbreviation Fix?
 

I have purple fringing on the right side of this photo. I'm not too shabby at photoshop but I can't get it to look natural when I try to fix it. Anyone have a tutorial?

Oh wow!!!. I totally screwed up the title. Chromatic Aberration I meant. :(

Have you tried fixing this in Camera Raw when you first imported it into PS? There should be a slider to fix the CA. If you're shooting in JPEG there's a way to open files in Camera Raw as well.

To me this looks like your flash was too close to the right edge of the frame and the light is bleeding in a bit and flattening the image.

Regardless of what it is, you can just start selecting the areas of the background on the right side of the image and then adjust the black levels and brightness with the 'curves' tool. You'll probably have to work on the fence independently of the bushes to get things to blend well, but you should be able to clean things up a bunch.
