An imaging apparatus capable of performing photographing in which a light emitting unit executes main light emission includes a photometric unit that executes photometry, a selection unit that selects a certain area in a photographing screen, and a control unit that determines a main light emission amount of the light emitting unit based on a photometric value acquired by photometry executed by the photometric unit when the light emitting unit executes pre-flash emission and controls, based on a position of the area selected by the selection unit, a light receiving amount of the photometric unit during a photometry period for acquiring the photometric value used for determining the main light emission amount.
