Abstract

965, 800. Printing from colour negatives. ILFORD Ltd. Aug. 30, 1962 [Nov. 10, 1961], No. 40357/61. Divided out of 965, 799. Heading G2C. In a modification of the process of Specification 965, 799 (wherein colour photographic material is exposed to red, green and blue light via a colour negative, using two light sources each transmitting two of the colours and filters are interposed to terminate each colour in turn) the light sources initially both provide white light. When sufficient light of the least required primary colour has been provided filters are interposed permitting passage only of its other two colours until sufficient of a second colour is provided whereupon the filters are replaced by filters permitting passage only of the remaining colours. The apparatus described in Specification 965, 799 may be used and examples are given of the use of such apparatus with negatives having differing colour requirements.
