A shutter apparatus includes a shutter base plate having an opening, a light shielding member movable to provide a closed state for closing the opening and an open state for opening the opening, and at least one processor or circuit configured to perform operations of a control unit configured to control the light shielding member configured to reciprocate relative to the opening so as to move the light shielding member in a first direction for a forward exposure and in a second direction opposite to the first direction for a return exposure. The control unit varies an exposure correction amount of the light shielding member between the forward exposure and the return exposure.
