An exposure meter has both function of an incident light type exposure meter for measuring an exposure value of an object by an incident light to the object and a reflected light type exposure meter for measuring exposure value of the object by a reflected light from the object. A latitude of a film is calculated from the exposure value by the incident light. The exposure value by the incident light and an upper and a lower limit values of the latitude are displayed on a display device. At least one exposure value measured by the reflected light is further displayed on the display device comparably with the latitude.
