摘要： An ophthalmologic photographing apparatus is disclosed. It comprises an observation light source for illuminating an eye to be tested; an observation optical system for forming an observation image of the eye to be tested and a corresponding image optically conjugating to the former; a photograph light source; a photograph device for photographing the eye to be tested; light volume measuring device formed of a number of light receiving elements for dividing the corresponding image into a number of picture elements in order to measure the light volume per each picture element and disposed at a position where the corresponding image is formed; an indicator formed of a number of indicating elements geometrically correlating to the light receiving elements and disposed at a position where the observation image is formed or otherwise at a position conjugating thereto; proper exposure value set-up device comprising an exposure value set-up circuit, light volume comparator and an indicator actuating circuit for actuating the indication segments having a correlation with the light receiving elements; and photograph light source control device for controlling the light volume emitted from the photograph light source based on the set-up exposure value information.
