PROBLEM TO BE SOLVED: To easily and securely measure reflected light and to set, appropriate exposure by means of measuring incident light in the same TTL camera. SOLUTION: Outer light reception parts 4 and 5 are installed in a body 1 of a camera. Illumination light of an object is made incident on the light reception parts 4 and 5, appropriate exposure can be detected and an exposure value can be set by measuring the incident light. In the measurement of the reflected light of TTL, it is measured by making not 18% gray but white which exists much in the object as a reference and the exposure value is given from brightness. |
