PROGRESS REPORT ON COLOUR KINEMATOGRAPHY
Jack H. Coote, M.B.K.S., F.R.P.S.*
Read to a joint meeting of the British Kinematograph Society and the Association of Cinema and Allied Technicians on 30th November, 1949
THIS progress report on colour kinematography1 must necessarily suffer from certain omissions and possibly some errors. For obvious reasons, it is very difficult for anyone to prepare a comprehensive and unbiased report when he is himself concerned with a particular process.
Figure 1 is a chart showing the processes which are in use to-day and their relationship to each other. The chart refers only to three-colour processes, and only to processes which are known to be commercially available.

Fig. I. Chart of three-colour processes in use to-day.
Appropriately, the chart commences with Technicolor under the section headed " Three Strip." Since it has often been said that the extremely efficient Technicolor organisation is " all strings and mirrors," one can only guess at the direction of any progress they are making with their processes.
The increases in the price of silver during recent years have made it more than ever desirable that Technicolor should commence their train of operations
