![]() Areas that fall between pure black and pure white, such as the transition area around the selection edges, will be blurred to a lesser degree depending on how light or dark they are. Any areas in the depth map that are pure black remain 100% in focus while areas that are pure white are completely blurred out. A depth map is simply a grayscale (black and white) image that Photoshop uses with the Lens Blur filter to decide which parts of the image to blur out and by how much. This is important because in a moment, we're going to be using this black and white alpha channel we've created as a depth map for the Lens Blur filter. The saved selection becomes a new "Alpha channel" in Photoshop's Channels palette.
