Paper Abstract

Criteria are studied and derived that relate lens MTF data to image quality of photographic prints. These criteria are based on the results of earlier experiments correlating MTF-data of photographic prints with observed judgements. Three criteria are considered, they are based on an integral over the weighted lens MTF, the lens MTF at a critical frequency, and critical magnification. The preliminary results show the limitation set by the photographic reproduction process, resulting in only small differences in image quality with standard lenses on axis. Improvements, however, are possible from lens performance off axis, by reducing the depth-of-focus range, by reducing effects like camera vibration, and especially from the photographic process.
