The black anodized finish is an integral part of the aluminum— can't chip, flake, or peel off. • ■ • 1 rouble-free performance is assured by the hermetically sealed construction of the Series II Snaplite. Its sleek black beauty typifies finer functional design — for the black anodized treatment, inside and out, is an integral part of the aluminum mount ... it can't flake, chip, or peel off! Enduring top performance is assured by the hermetically sealed mount, which excludes oil and moisture, and eliminates need for disassembly. Cleaning time is cut to a fraction — handling is minimized — danger of damage is sharply reduced. Light-weight aluminum mount cuts vibration to a minimum. 1 Brilliant pictures result from speed of f/2.0 in focal lengths from ZVz" through 5". All optical surfaces are treated with durable anti-reflection coatings for still greater brilliance and contrast. ILOLLAlOltltfOfi 4* 2 Franklin Avcnu* Brooklyn 11. N..

This would be around 1927. Many hundreds of feet of ortho negatives were dyed in our laboratory in order to conclude the tests to prove the practicability of this method of photography as to color value, resolution of the negative images and register of the pair of negatives to positive film. Needless to say, each point was proved to our complete satisfaction. This then became the first commercial use of bi-pack as a means of color photography. All experiments and tests were conducted by the writer. Commercial Bi-Pack Film Having determined that bi-pack would become our means of obtaining color value negatives, it was decided that it was inadvisable to continue to dye the front negative in our lab because conditions were not satisfactory tor this important operation. With this thought in mind we approached E. I. DuPont de Nemours & Co. We explained our desires and showed both negative and positive tests, which interested the company to the point where they decided to manufacture and sell a bi-pack negative of a nature similar to our tests. The first important use of DuPont's bipack — which we termed Rainbow nega tive;— was by Jerry Fairbanks, President of Scientific Films. His "Strange As It Seems" films were all photographed using bi-pack. Mr. Fairbanks has continued to use this system, through the many years, on his various shorts. Eastman subsequently pla ■ i a product on the market of a similar nature to DuPont's. Today bi-pack is in universal use, both for shorts and features. The first ambitious attempt to produce a major feature by this system was M-G-M's "Gallant Bess," produced in Cinecolor by Harry Rapf and photographed by John Boyle, now in general release. Hal Roach studios have contracted to produce a number of features in Cinecolor by the bi-pack system. Five of these have been finished as far as production is concerned. The present high quality of bi-pack photography, plus the Cinecolor method of producing release prints, is creating more than a passing fancy in the industry and high budget pictures are currently before the cameras.
