A photometric apparatus includes an exposure value calculator for calculating an exposure value based on light data from a photo sensor and an inputted photosensitivity; an exposure value difference calculator for calculating a difference between a calculated exposure value and a reference exposure value; a gamma characteristic provider, which provides a gamma characteristic concerning a relationship between the exposure value difference and a gradation value of digital data; a gradation calculator for calculating, based on the exposure value difference and the gamma characteristic, a gradation value of digital data in connection with an object having the calculated exposure value when the object is photographed at the reference exposure value; and an indicator for indicating the calculated gradation value of digital data in connection with the object.
