JimBobCarl, the mystery is taken out once you know how to handle the Alpha. Regardless of what program you use, if you know how to subtract the alpha, you can substitute anything in its place. Thats the gist of it all. Not only that, but consider that you can then create a new alpha color after youve composited your first effect. Now, on top of your previous alpha composition, you can add yet another, then another and so on down the line.
