An intensity of a flashlight projected from a flashlight projector is at
the maximum outside a photographic area. A plate protuberance is formed in
a center of an inner face of a protector. A part of the flashlight emitted
from a flash tube is reflected on upper and lower faces of the plate
protuberance so as to tend into the outside of the photographic area. The
intensity of the flashlight emitted into a center of the photographic area
is deflected on a wedge of an end of a plate protuberance. Thus,
distribution pattern of the flashlight is changed by the plate
protuberance, and the intensity of the flashlight becomes 1.0-1.5 LV
smaller in the center of the photographic area than on upper and lower
limits thereof. A main subject in a smaller distance is not overexposed,
and a background in a larger distance is not underexposed.
