Cross processing (or xpro) refers to physically processing a film in a chemical solution intended for another type of film, resulting in unnaturally coloured photographs giving them a surreal quality. This can be done for photographs or movies, Tony Scott’s Domino being a recent example.

Thankfully, Adobe Photoshop makes it easy to create your own cross processed images in a few simple steps.
Tutorial:
First off, find an image that lends itself to the process. It can be a portrait or landscape, whichever you like.
I’ll use this:

1 - Open the image in Photoshop. Sharpen, lighten it; whatever needs to be done.
2 - We’re going to be working with Curves now. For that, go to Layer à New Adjustment Layer à Curves

3 - In the new window, we’ll want to change the red, green, and blue, so click on this:

4 - Starting with RED, we change the curve to look something like this:

5 - Do the same for green.
6 - For blue, we do the exact opposite, so it looks something like this:

7 - In the end, your curves should look something like this:

Red and green on top, blue below the middle. Click OK and you’re done!
So, we go from this:

To this:

Play around with the settings. It can be as subtle or as intense as you like.
