A strobe diffuser attachment for a camera, includes a diffuser body adapted for attachment to a camera, a pair of spaced diffuser lenses mounted in the diffuser body and adapted to be located in front of a range of different integral strobe locations for a camera attached to the body, wherein the pair of diffuser lenses are adapted to serially diffuse light emitted from an integral strobe of a camera attached to the body. A distance measurement device uses a pair of light beams which intersect at a repeatable distance from the diffuser body to readily enable positioning of an object to be photographed at that repeatable distance.
