Abstract:
An electronic flash controlling device controls a flash light emitting unit that performs a main light emission and a preliminary light emission prior to the main light emission. A maximum preliminary light emission quantity setting unit sets a maximum preliminary light emission quantity for the preliminary light emission during which a smaller quantity of light is emitted than a maximum light emission quantity based upon maximum light emission quantity information regarding a total light emission quantity which the flash light emitting unit is capable of generating.
