Abstract
The importance of the different parameters determining image quality in photographic microreproduction is discussed. In a first section it is shown that the slope of the H. & D.-curve is limited, among other factors, by the modulation transfer function of the complete system. In a second section the relation between information capacity. resolving power and practical image quality is considered. It is shown that a linear combination of image spread and granularity provides a good criterion for image quality.
