The operation of a Morse Aerial Film Processor was investigated with the object of improving processing, so that statistically significant variability of the gamma of the film would be reduced. The possibility of estimating the mean gamma of the whole film with the aid of sensitometric exposures at the end of the film was examined. By changing the attitude of the Processor and discarding some footage at the ends of the film, variability of gamma across the width and length of the film was reduced to insignificance. The reduction in variability made it possible to estimate the mean gamma of the whole film by placing sensitometric exposures at one end of the film.
