Adobe photoshop cs



Hi. I have adobe photoshop cs on my xp machine. I want to use one of those blue screen backgrounds/scenes that come with digital cameras. I can’t find anywhere in the Help section on how to do this. I know my picture should get superimposed and then anything blue will be replaced by the picture but I’m not having luck. The adobe website is no help either. Any clue on how to do this?


sounds like alpha blending - but no idea how to implement.
