Abstract
A photography system includes: a camera containing a first communication unit; and a photography illumination device containing a second communication unit, wherein: the camera wirelessly transmits from the first communication unit to the second communication unit a first signal that commands, from the camera side to the photography illumination device side, a preparatory flash emission that precedes a main flash emission during photography; the photography illumination device wirelessly transmits from the second communication unit to the first communication unit a second signal that includes flash emission timing information of the preparatory flash emission, and that carries information, from the photography illumination device side to the camera side, as to the effect that the first signal has been received; and the camera starts photometric processing during the preparatory flash emission based upon the flash emission timing information.
