16-MM COLOR METHODS 503
little over a decade ago, a commercial duplicating business was born. Even at that early stage, the advantages of color and sound in 16-mm were appreciated; a survey of certain industrial film users showed that more than 90% of those canvassed wanted color in their 16-mm sound films — and only Kodachrome was able to give it to them. The rapid growth of Kodachrome duplication, therefore, was not entirely unexpected.
Available Types of Kodachrome
Kodachrome for duplicating is sold in a single contrast and color balance: duplicating, for 2900K source temperature, code EK 5265. 16-mm Kodachrome is designed to be used with a specified arrangement of filters for "balancing" purposes and with the lamp operated at the specified temperature of 2900K. Further data on the process will be given later.
The duplication of Kodachrome has grown in volume to the point where each of several laboratories not connected with the film manufacturer is printing several million feet per year. The total handled by all users is a truly large item when we remember that the average cost is approximately 12 cents per foot compared with approximately 2.5 cents per foot black and white.
Ansco is also marketing duplicating film ; although the result is quite different from that with Kodachrome, the general methods are quite similar. The competition can be expected to become especially keen when simplified methods for reducing resolving power losses in duplication have been satisfactorily worked out. As a step in that direction, Ansco has anounced a one-strip separation black-and-white film in which the contrast has been adjusted to the requirements of color duplication and each color frame is represented by its three components printed sequentially along the one-strip separation film.
Competitive Positions of Present-Day 16-Mm Color Methods
It would seem worth while at this point to give some thought to the future, as signs point to a still further increase in volume of 16-mm color film. For most purposes, the present Kodachrome product is quite satisfactory. There are several competitive factors, however, that are the imponderables of the future.
First, there is the marketing of AnscoColor Film. At first glance, AnscoColor film would seem to be in the fortunate position of sharing the
