This Instructable will teach you how to make Channel Art.
> An advanced image editing program: Gimp, Photoshop, Pixelmator, Paint .Net etc.
> Some time.
Step 1: The Channel Art template
The Channel Art template is a .PSD, so you’ll need Photoshop, but I often use Pixelmator for Mac to do image editing, which is really the same thing. If you’re looking for a free program to do this editing, look into Paint .Net or Gimp. The interfaces of all image editing programs are fairly similar.
Open up the template and study it for a minute. If you're new to image editing programs, play around with a few controls, particularly the ones which have to do with hiding/showing and adding/deleting layers.
