This is a very simple tutorial - it is going to basically explain the details of layers in graphics editing programs, and what they do.

I use PSP, so there will be no explanation for any PS only layers, such as pin light :]

 Today, I will be writing about the main layers - Darken, Lighten, Colour, Multiply, Screen, Softlight and Exclusion.

{ a basic description of each layer and how to use them }
