We use Optical Character Recognition (OCR) during our scanning and processing workflow to make the content of each page searchable. You can view the automatically generated text below as well as copy and paste individual pieces of text to quote in your own work.
Text recognition is never 100% accurate. Many parts of the scanned page may not be reflected in the OCR text output, including: images, page layout, certain fonts or handwriting.
Kodachrome film is spliced in the same way as black and white film. It is not necessary to scrape off the bluish-green coating which is left after the emulsion is removed. Kodachrome is now processed in the United States at the Rochester, N. Y., plant of the Eastman Kodak Company; in Chicago by Eastman Kodak Company, 1727 Indiana Avenue; and in Los Angeles, Calif., by Eastman Kodak Company, 1017 North Las Palmas Avenue. Processing laboratories will soon be opened jn other cities. DUFAYCOLOR PROCESS—Dufaycolor, which has been widely accepted in this country, is an English importation, be- ing the result of long experiments backed by Spicers, Ltd., of London and Ilford Ltd., outstanding English photographic manufacturers, as well as other interests which provided the financial backing and technical guidance which made the pro- cess possible. Dufaycolor has gone even farther than Eastman in that full color film is now available for practically every type of camera from Leica to professional movie cameras, and is fur- nished in cut film and roll film as well as in 16mm. motion pic- ture film. Duplicate positive transparencies in these types of film can be made from the master positive. The process takes its name from Louis Dufay who has been associated from the earliest days with efforts to produce color-screen film rather than plates, so that motion pictures could be projected in natural colors. In Dufaycolor the color matrix consists of regular areas of the three additive primary colors, blue, green and red, arranged in a geometrical pattern. Many plates having such a screen pattern have been made but the ease and regularity with which Dufay’s invention can be applied to the manufacture of cine film in millions of feet has made it one of the most important advances in modem photography. The application of a microscopically fine screen, or reseau as it is called, to a film base by mechanical means on a regular and comparatively inexpensive commercial basis, particularly enhances its value as an acceptable medium for use in the professional motion picture field as well as all other branches of photography. Dufaycolor film consists of ordinary film base of suitable thickness. Cellulose acetate base has been used exclusively 98
