In the second video in this series of Photoshop Secrets, we look at how to make very precise changes to your image based solely on colour.

This allows us to break our image down to primary colours, so that we can then start enhancing specific parts of our images within a particular colour range. If it sounds complex, after 2 minutes of this video you will see that it is, in fact, very simple!
