Abstract: A study is made of five criteria that are being used with photoelectric instruments to determine camera exposure. The only really satisfactory method appears to be the use of maximum and minimum brightnesses for the portion of the scene range over which the photographer desires gradation. The exposure time is then found by relating these two points to the characteristic curve of the film. The poorest method seems to be the popular one of determining exposure by the average scene brightness as measured with a photoelectric exposure meter.
