Abstract
In the disclosed flash device, a flash portion is shiftable from an ordinary flash position to a bounce flash position. Automatically controlling the illuminating angle of the flash portion on the basis of the focal length of the lens of the camera can degrade the effect of the flash photography. This is obviated by controlling the illuminating angle for bounce flash independent of the information on the focal length of the lens.
