Abstract

16,999. Smith, L. Aug. 22. Sensitized plates and films.-A photographic film is constituted by two gelatin-silver emulsions or sets of emulsions, and an intermediate transparent flexible base of non-absorbent material, such as celluloid, the emulsion or sets of emulsions on the one side of the base being relatively faster than those on the other side. Either emulsion may be isochromatic.
