Abstract
147,621. Goetz, H. July 8, 1920. Addition to 169,233. Silhouettes.-Alternative methods are described for making silhouettes by using a coloured background, and only one filter for taking one of the negatives, or even dispensing with filters. In one alternative two negatives are taken of the object in front of a yellow background, one on an orthochromatic plate through a yellow filter and the other on an ordinary plate insensitive to yellow. In one negative, the background is black and in the other it is transparent. Other colours for the background can be used and the use of filters avoided by using plates so sensitized as to obtain negatives, in one of which the background is clear and in the other is black. In the Specification as open to inspection under Sect. 91 (3) (a) a method of inserting the photographed object into another picture is described. A diapositive of one negative is combined with the other negative to produce a silhouette, which may be interposed between a third negative to be printed and the printing paper, so that in the print there is an unexposed portion corresponding to the silhouette. The negative of the original silhouette object having the background black can then be printed into this space giving the combination print. This subject-matter does not appear in the Specification as accepted.
