One of the first art projects we did as kids was to create a picture out of cut-up pieces of paper. The fun was in deciding which color or finish of paper best resembled its real-world equivalent. In later years, after exposure to Chagall cut-outs, we saw that these paper collages are not confined to youth.

Since most of us deliver our artwork in digital format, it makes little sense to sit around cutting up paper to make a collage. Even if you scanned the finished piece back in to your computer, the result would lack the tactile finish of the orginal.

But if you like the look of paper collages, you can make your own digital paper in Photoshop and then use masks to "cut out" the desired pieces. It's quick, easy, and requires no glue. Best of all, with this technique you're not squandering our forest resources.

In this excerpt from "Adobe Photoshop CS Creative Studio," Luanne Seymour Cohen shows you how to create collages out of digital rather than pulped paper.
