A camera comprises a storage-type photometering sensor that detects some of light from a subject; a control device that controls an auxiliary illumination device so as to perform a preliminary light emission through a single-shot light emission and controls the storage-type photometering sensor so as to detect the subject light stored over a storage period matching a length of time over which light is emitted during the preliminary light emission; and a setting device that sets a light emission condition under which the auxiliary illumination device is to emit light during a flash photographing operation based upon detection results obtained at the storage-type photometering sensor.
