text: Start slapping. It's Photoshop. \n\nI can tell because it's a PNG. When I opened it in Fireworks, which is a PNG editing program, it shows a single bitmap image in the background layer -- which is exactly how Photoshop saves a PNG after you "flatten" the image (merge all the layers into one) -- and since this is a composite image made from several images, that pretty much seals it.\n\nAnother dead giveaway is the way the masks were applied to the backgrounds of each individual (that is, the background colors of each image were "knocked out", or masked). \n\nIt takes a pretty good image editing program to make masks as good as the ones used here, even if the subject is against a black background; in fact, it actually looks like these were made using clipping paths, which is a dead giveaway that Photoshop was the tool used.\n\nSo, if I was to guess how these were made:\n\n1. Each band member's individual photo was turned into a clipping path, to knock out the background.\n\n2. Each was then placed on a the final canvas and scaled to fit.\n\n3. Each member was then overlaid with a 20% opacity solid color, with a blend from the color it was starting at to the color it was matched against. That was probably done with a plug-in.\n\n4. The whole thing was flattened and shipped out to PNG, probably in ImageReady.
