Abstract
An apparatus and method for determining a film development parameter and a camera exposure setting to compensate for the luminous dynamic range of a subject being photographed. In a semi-automatic embodiment, information corresponding to desired film densities for two areas of the subject matter is manually inputted to the apparatus, which is then pointed towards the two areas. In an automatic embodiment, information corresponding to desired film densities for the brightest and least bright areas of the subject to be photographed is manually inputted, the entire subject is automatically scanned by a vidicon or equivalent means, and the brightest and least bright areas of the subject are automatically detected.
