发明名称 Multicolor antiquation screen
摘要 An improved method for producing multicolor photographic images which resemble color photographs made prior to 1936. Light expressing a photographic image is passed through a transparent multicolor screen (20). Visual characteristics of the image are altered so as to produce darkened tonality, loss of acuteness, muting of hue, and a general sepia color cast.
