High Frequency Response from Variable Width Records as Affected by Exposure and Development
The photographic treatment of variable width films is a subject of much interest to those who are concerned with the problem of obtaining the maximum high frequency response from a given type of film. An experimental study of the effect of photographic treatment upon the 6000-cycle output from Eastman positive film has been made. The results of this study show how the 6000-cycle output of a print varies with the density and gamma of the negative and the print. The variation in negative output with density and gamma is also shown. Under optimum printing conditions the output of a 6000-cycle contact print (made on the frame printer) is 92 per cent of that obtained from the best negative.
