16-MM ANSCO COLOR PRINTS 145
Ansco color camera film, Type 735, may be used in regular 35-mm professional cameras without any conversion and, therefore, Bell and Ho wells, Mitchells, or even Eyemos are satisfactory for production work. That fact was very important in the requirement of the indust rial production job to be described. There were assignments to be met within three months' time, scattered from California through Colorado, Texas, Kentucky, Mississippi, Illinois, Iowa, Minnesota, North Dakota, and Oregon; and half a dozen cameramen, with a wide variety of equipment, had to be assigned to shoot the color footage under a great variety of field conditions. These varied from flying over the great wheat fields of the Pacific Northwest with an Eyemo in order to climb the steep hillsides to film the harvest ; to standing in almost knee-deep water in the rice fields of Mississippi, no place for heavy cumbersome color cameras, and the Eyemos and lighter Bell and Howells came in handy and turned in creditable color photography. In some locations cameras had to .be secured on top of moving machines, and one Mitchell was even tied down inside the grain tank atop a huge combine moving over rough ground.
No photography was planned before 10:00 o'clock in the morning, and seldom after 4:30 in the afternoon, and bright sunlight was a prerequisite. As a result, a fairly evenly exposed original camera film was obtained. Approximately 15,000 feet were shot during those three months. It is recommended that one single-emulsion number he' used on each production as there is, as in all color processes, some color-balance change in succeeding emulsion runs. It was also found that pleasing effects and good definition in dark areas were obtained with cross, and even partial, backlighting. Naturally extra caution was taken in exposure reading and our camera crews carefully considered the subject before deciding on a lens stop.
After the original camera film was exposed, it was shipped to the Houston Color Laboratories in West Los Angeles for developing and printing a "daily." During the past 10 months this laboratory has been processing approximately a half -million feet per month of Ansco color film, and is equipped to turn out a daily print within 48 hours. The processing of Type 735 camera film is almost identical to a description by Forrest,2 except for a somewhat shorter developing time in both the first developer and the color developer.
In making a daily print from the original camera film, each scene is not timed for density and color balance, but an over-all average printer exposure and an average filter balance are determined and the daily is
