In a complete imaging system, consisting of a camera and a camera lens, four black and white films, an enlarger, a print made from each film and a number of observers, the resultant images were judged subjectively. The system was also evaluated by four acutance models. When the acutance ratings were compared with the sharpness ratings there was not a significant correlation between the two ratings. The author believes that there would be a better correlation between the two ratings if the acutance models were used under the same conditiobs and the same constants as they were formulated under.
