Abstract

511,172. Colour photography. LASSUS ST. GENIES, A. H. J. DE. Nov. 9, 1937, No. 30782. Void. Convention date, Nov. 16, 1936. [Class 98 (ii)] The colours of the projection filter for lenticular films are complementary to those of the taking filter. The colours of the taking filter may be blue, green and red, and the colours of the projection filter blue-green, yellow and purple. Taking and projection filters for spherically lenticulated films are shown in Figs. 4 and 4a having coloured zones b, v, and r, and B, J. and P respectively. Taking and projection filters having various arrangements of coloured zones, including taking filters with inclined zones are shown in the drawings. Dominants in one or more of the colours can be compensated for in projection copying by screens arranged in a diaphragm of the copying system obliquely to the lines of separation.
