The art of still photography and the art of filmmaking have always been closely related: Think of Stanley Kubrick, whose experience as a photographer no doubt influenced his stylized films, or revolutionary photographers such as Robert Frank and William Klein who also shook things up with their experimental films. Today, however, the distinction between filmmakers and imagemakers is practically nonexistent. Rapid technology advances and exploding demand for all kinds of visual storytelling have led to a new creative hybrid -- photographic artists who migrate seamlessly between the still and the moving image. In the following special section, American Photo goes behind the camera with six of these visual chameleons to uncover the secrets to their success. All of them have learned to capitalize on their multifaceted talents to help them go further in their favored field, be it hard-hitting photojournalism or beat-dropping music videos. But most important, they recognize that as the walls between mediums come down, those who can straddle the divide will be the ones still standing when the dust settles.
