The equation of the Additive system of Photographic Exposure (APEX) in camera system has been derived. Simple thin lens has been used to approach the real lens system. The basic equation of camera exposure should be derived firstly by analyze both of geometry and photometry of image formation. The APEX equation would be obtained by modifying the basic equation to the form of exposure value system that difine by base-2 logarithm number. Then the calculated of the APEX eqution would be drawn in a diagram line.
