Attached Link: Creating the Cover for Love and Magic

Compositing involves making two or more images look like one image -- for example combining a background photo with a Poser render, so that the rendered Poser figure looks like it's part of the photo.

There is no one set of good tutorials on this -- just read far and wide, or experiment with Photoshop as much as you can. I do a lot of compositing in my cover work, and 99% of my techniques are self-taught ... just stuff I discovered on my own while playing in Photoshop. We can all help you discover your own techniques, but it'll be much easier to do if you have more specific questions, since compositing can be done in so many different ways and for so many different reasons.

I'm including a link to one of my photo compositing examples so that you can see what can be done in combining several photos to make one.
