Something More about Progress in Subtractive Process Color Cinematography
Frederick E. Ives · Transactions of the Society of Motion Picture Engineers · 1927
The brief paper which I now submit is supplementary to the one which I presented at the last Washington meeting of the Society, and is essentially a report of progress. In the former paper I stressed the fact that I started out with the idea of producing color motion picture films of satisfactory quality on ordinary positive motion picture film, and by the simplest and most direct means possible, and that I have consistently adhered to this scheme. I have continued experiments with a view to further simplification and speed of operation.
