In the previous paper, we proposed a new concept of photographic speed “Quality-Aimed Speed” for color negative film which has a very wide exposure latitude. The quality-aimed speed which based on signal-to-noise ratio was determined by examination of subjective image quality for 8×10 inch prints enlarged from 135 format color negatives. In photographic print viewing practics, however, fairly wide range of print size was observed in approximately same viewing distance disregard to their perspection. In this case, it is considered that the subjective image quality of the color print is a f unction both of the speed and the print size. In this paper, relationship between the print size and the photographic speed which ensures the equi-picture-quality was examined.
