Abstract: Crane's objective method for rating picture sharpness, SMT acutance (system modulation transfer acutance), has been applied to systems for producing small-format color prints. Although calculated sharpness values agreed well with experimental results, the way in which changes in format affected these values was unclear. A systematic investigation of the relationship between size of format and SMT acutance for original films and print films showed that changes in format were equivalent to changes in film-sharpness characteristics for the stages involved. Computational analyses of model systems are used to illustrate the usefulness of sharpness calculations in estimating the sharpness potential of a given color system. Such calculations can also aid in planning system improvements.
