Atmosphere scatte#ing, lens flare, and turbidity at the emulsion are each given attention. Nuclear test films from Operation Castle are analyzed primarily for contrast rendition and edge sharpness, in the hope that methods will be found to improve photographic results in the future and in addition provide some basis for predicting such results under given weather and photogrammetric conditions. 801.
