Abstract
A copy stand for supporting a camera having a built-in flash device to photograph a subject in an exposure area. The stand comprises a continuous sheet of paper board folded and coupled to itself to form a generally tubular section adapted to surround the subject in the exposure area and establish the position of the subject relative to the camera and flash. The tubular section includes a baffle, which blocks direct flash illumination of the exposure area, a first diffuse reflector, which directs flash illumination around the baffle and toward the exposure area, and a second diffuse reflector on the opposite side of the exposure area from the first reflector. The second reflector redirects illumination from the first reflector back toward the exposure area, thereby illuminating the subject area from multiple directions.
