Photo of a "Geoffroy's Tufted-ear Marmoset," a small, New World monkey

Behind the Photography Scenes:

OK, I admit that I cheated here. I shot this photo at the National Zoo in Washington, D.C., where I found this Geoffroy's Tufted-ear Marmoset at the "Small Mammal House." The marmoset lived in a small, glass enclosure with an unattractive white and green-hued wall in the background. To make the photo seem more natural, I added a pretty, blue-clouded sky using Adobe Photoshop CS2, and employed a layer mask on the sky layer to apply the sky only to the background areas.
