Compositing Images

As we explained in the last chapter, the number one problem in making selections and compositing images together is edge spill, where some of the background color gets picked up as fringe along the edges of your selection. There are a number of methods for getting rid of edge spill, but most of them involve simply cutting away at the edge pixels rather than removing the background color from the mix.

Now, to the rescue, comes the Extract feature, which is designed to search out edges, erase pixels, and—most important—perform edge-color decontamination, where Photoshop distills out background colors while leaving the foreground colors. It's almost like magic, and would be extraordinary if it really worked for more than a handful of images.
