This Photoshop CS5 tutorial will demonstrate how to change the background in a portrait without losing much detail. I’ll also show you how to achieve that in earlier versions of Photoshop. Before Photoshop CS3, making fine selections was fairly difficult. Refine Edge came to the rescue in CS3 and makes fine selections a snap. Before that there were a few ways to achieve fine selections, the most popular being Channel Masks. First I’ll show you a Channel Mask technique and then I’ll show you Refine Edge for those who have CS3 or later.
