ABSTRACT:
A flash photography system arranged to make preliminary emission and to control main emission according to a value of light measured at the time of the preliminary emission is capable of adequately performing main flat emission by making the preliminary emission in the mode of flat emission and controlling a peak value of the main flat emission according to data of light measured when the preliminary flat emission is made.
