Dennis Cook became interested in photography when he was introduced to the 35mm camera by a Vietnam Vet. He began to master the fundamentals of photography first by independent study and then through formal instruction at the Germaine School of Photography in New York City. Cook also credits the influences of two intellectual fathers: the "technical expertise of Ansel Adams" and the "artistic and interpretive genius" of Edward Weston.

"The land never complains or tells me what to shoot," says Cook, speaking on why he usually chooses western geological phenomena over humans as subjects. "To me it seems easier to drive 2,000 miles than to ask someone to pose. People are never happy with themselves." Some of his "favorite spots" are superbly documented, primarily in black and white: the Grand Canyon, Death Valley, Sand Dunes of Oceano, the rocky coast of Maine, and the Southwestern architecture of New Mexico.
