ABSTRACT:
A lower part of a reflection mirror is cut away to admit light flooding downwards in a special photographing situation, for instance, close-up photography, by slidably removing an auxiliary movable mirror part from the cut away part. By sliding the movable mirror part to cover the cut away part of the reflection mirror, a normal light angle is obtainable. Thereby, both close-up flash photographing without any parallax of flash light, as well as, normal flash photographing with a correctly flooded flash light are obtainable.
