A method and apparatus for monitoring the buildup of fog in a non-silver free radical film while a latent image in said film is being optically developed, wherein the buildup of fog is sensed by radiation directed at a non-image area of said film and reflected from said area to a sensing device. The reflected radiation is altered as the buildup of fog takes place.
