Abstract
In the present invention there is provided a plurality of photosensitive elements arranged in a symmetrical pattern around a central circular area. The area surrounding the central area is formed of a square area having the circular area at its center with the square area divided into four equal quadrants. The next area is rectangular in shape and surrounds the second area. The rectangular area is formed in four equal sections with each of the corners of the square area lying along two adjacent edges of the rectangular areas. A selection means is provided for selecting the output signal from any one the photodiodes or for selecting the output signals from any combination of two or more of the photodiodes so as to accentuate the responsiveness of the light meter to a selected area or feature of the image to be photographed.
