Description

ABSTRACT:
A multiple photoflash lamp unit is connectable to a camera in different orientations in each of which a different group of the lamps is relatively farthest from the camera lens axis. The lamps are arranged so that in any of the orientations of the unit with respect to the camera, only the group of lamps relatively farthest from the lens axis will be flashed. This reduces the "red-eye" effect that can occur when the flashing lamp is close to the lens axis, undesirably causing a red coloration of the pupils of eyes of people in the picture.
