ABSTRACT:
A method and apparatus for reproducing subject tone in a photograph in a manner predetermined by the photographer comprises assessing the tonality of the subject with reference to a tonal scale by simultaneously viewing both the subject and the tonal scale through a viewfinder of a camera or a reflected light meter. The exposure parameters of the camera are then adjusted to insure accurate reproduction of the tonality of the subject, as assessed by the photographer with the aid of the tonal scale.
