Description: |
| Abstract:
My present invention relates to color photography and particularly to means for better carrying out the process involving the use of a plate or support carrying the transparent colored dots or lines through which the exposure is made, and if desired viewed, and it has for its objects to provide a film support or plate which is complete in itself and may be used in an ordinary camera without the use of a separate ray filter. To this end the invention consists of a suitable transparent support, preferably of flexible transparent material, such as cellulose, either nitrocellulose or acetyl cellulose or even gelatin, having thereon or therein transparent or .translucent dots or lines in the colors usually employed in color photography as red, green and blue, and over this a= sensitized photographic emulsion preferably of gelatin, said support having on the face or side which, when the exposure is made, is next to the lens of the cam- era, a coating or thin film of gelatin or other suitable material containing coloring matter suitable to act as a correcting filter.
Claim:
A polychromic plate for use in color photography embodying a support having" minute differently colored transparent areas, a sensitized emulsion on one side thereof and a ray filter screen embodying removable coloring matter formed on the opposite side. |
