Abstract
An imaging apparatus capable of imaging using an illumination apparatus includes an acquisition unit configured to acquire object luminance information, a calculation unit configured to calculate an exposure control value based on the object luminance information acquired by the acquisition unit, an exposure control unit configured to control exposure using the exposure control value calculated by the calculation unit, and an exposure fixing unit configured to set an exposure fixed state in which the exposure control value calculated by the calculation unit is fixed as the exposure control value to be used for exposure control, wherein the exposure fixing unit is configured to cancel the exposure fixed state when a state of the illumination apparatus is changed in the exposure fixed state.
