By separately adjusting the red, blue and green channels using a Curves adjustment layer in Photoshop (or by using a Curves plug-in for Photoshop Elements), you can achieve a cross-processed look. Here's an article discussing how I did this (and from which I took the historical information in the first paragraph). Here's my first attempt at cross processing, albeit on a sign. Actually, on this version, I duplicated the background layer of the original and used the SmartCurve plug-in for Photoshop Elements on that layer to do the cross-processing (users of the full-blown version of Photoshop can just use a curves adjustment layer). Underneath that is a channel mixer layer to convert the image to black and white. So, what you end up with is marginally colorized, cross processed black and white. Not really what I was looking for, but the full-color version just explodes with green grass, so for the full picture, it's a good compromise.
