In this tutorial, I’ll recreate the effect of Cross Processing – the method of developing slide film with the chemicals for developing print film.

Here is the photo I’ll be using:

Firstly, we need to adjust the levels; So Layer > New Adjustment Layer > Levels.
Rather than manipulating the layers together as RGB, we’ll do them one at a time to create the desired effect.
Here are the settings I’ve used for each and a small picture of the result at that stage.

Red:


Green:


Blue:


In the layers window – Right click on the original picture layer and select Duplicate. Then move this above the levels adjustment layer

Now – with the duplicate layer selected, Ctrl + U to open the Hue/Saturation controls. Increase saturation to around 55-65 to accentuate the colours.


Set this layer’s blend mode to Hard Light.
If you’re unsure what blend modes are, what they each do, or which one to pick; I wrote a tutorial on this a while back – Found Here

Now, to add a photo filter. Layer > New Adjustment Layer > Photo Filter.
Pick Cyan and density of around 85-90%, then Ok.

We need to fill the mask of this adjustment layer with black, so Shift + F5 and pick black at 100%.
Take a white brush with a soft edge and opacity at around half and start to paint over the background – avoiding the model and the yellow signs.

Here’s what my mask looks like to give you some idea!

When you’re happy, merge down all layers with Ctrl + Shift + E and take the sponge tool (found nested with Dodge and Burn)
Set the mode to Saturate and flow at about half. Using a soft edged brush, go over any yellow or red areas to accentuate them further.

Thats it! Here is my result:
