Abstract

1460193 Photographic masking H H ROSS 5 Feb 1975 [7 May 1974] 19978/74 Heading G2X A photographic masking frame comprising a base-plate 10 and an apertured plate 11 adapted to overlie a photographic sheet 16 is used in combination with a set of masks 12 which fit inside the aperture 13 of the plate 11 so as to permit selective exposure of the sheet 16. Supplementary overlay members fit inside the plate 11 to reduce the total exposure area, a set of masks being associated with each such member. Pins 18 and slots 19 co-operate to hold the sheet 16 in position. The plates 10 and 11 may be urged together by magnetic means.
