Cross Processing

I wanted to adjust the levels of different colours (mainly blue, green and red) in some of my photographs so I used the Curves tool on Photoshop in order to do so. 

First I opened up one of my images in Photoshop and saved the file in a different name in order to not work on the original copy of the photograph. 

Then I clicked on the Layer menu (located at the top of the program) and added a New Adjustment Layer and selected Curves. 

A chart then appeared so I could manually change the colour tones within the image. I first chose to edit the green section and moved the curve so it was lower down at the bottom of the curve but went higher nearest the top.

Next I chose to edit the blue section and I chose to take out a lot of this colour and moved the curve below the original line and a 'U' shape. 

Finally I chose to edit the red, adjusting the Curve so that it was a slight 'S' shape.

I then repeated this process (varying it slightly on some for different results) on different images in order to create different results.
