KODAK EKTAR KODACOLOR •••1' GOLD FILMS HONORS Namic Negative
by Jack and Sue Drafahl EKTAR If you liked the first two Ektar films Ko- dak released earlier this year, then you're going to love the two newest additions to this exciting film family. Kodak just released Ektar 25 Professional, and the medium-speed Ektar 125. Both films are modeled after the first two films, qi Ektar 25 and Ektar 1000, but boast An Unqualified, \ several improvements. EKTAR 25 PROFESSIONAL FILM Categorically Loud, § The best way to describe the differ- Rave Review! \ Ektar 125 is an extremely practical film, with much wider exposure latitude than the slower 25-speed Ektars. ence between Ektar 25 and the new professional version is to use a correla- tion we sometimes give our photo stu- dents. If you went to the finest winery, and selected their top-of-the-line vin- tage, you would be selecting Ektar 25. Now, if you were to select those few bottles that were aged to absolute per- fection, then you would be selecting Ektar 25 Professional. Kodak's manufacturing plant sees to it that all Ektar 25 film must fall within the tight tolerances they set for each distinct layer of film. When the specifications on a certain emulsion are found to be a perfect match in all areas, it becomes Ektar 25 Profession- al, and is refrigerated at that point. This better-than-best film is recom- mended for the professional photogra- pher demanding large enlargements from a 35mm negative.

Is THE EDITOR there any way I can tell? Mr. C. B., Nashville, Tenn. Comments: I thought you might be interested in an unusual sequence I shot recently. I observed a big snapping turtle come into my yard and, knowing that she was going to dig a hole and lay her eggs, I loaded my camera and took some wonderful shots. I watched the eggs, and 3½ months later when they started to hatch, I made shots of the baby turtles coming out of the eggs and learning to walk. Later I made appropri· ate titles, and came up with what I call a creditable color movie. Mrs. B. E. C., Moorestown, N.J. A. Yes. Take a look at the end of your film.

KODAK MILESTONES 1879 - Eastman Invented an Emulsion-Coating Machine Which Enabled Him to Mass- Produce Photographic Dry Plates
KODAK MILESTONES 1879 - Eastman invented an emulsion-coating machine which enabled him to mass- produce photographic dry plates. 1880 - Eastman began commercial production of dry plates in a rented loft of a building in Rochester, N.Y. 1881 - In January, Eastman and Henry A. Strong (a family friend and buggy-whip manufacturer) formed a partnership known as the Eastman Dry Plate Company. ♦ In September, Eastman quit his job as a bank clerk to devote his full time to the business. 1883 - The Eastman Dry Plate Company completed transfer of operations to a four- story building at what is now 343 State Street, Rochester, NY, the company's worldwide headquarters. 1884 - The business was changed from a partnership to a $200,000 corporation with 14 shareowners when the Eastman Dry Plate and Film Company was formed. ♦ EASTMAN Negative Paper was introduced. ♦ Eastman and William H. Walker, an associate, invented a roll holder for negative papers. 1885 - EASTMAN American Film was introduced - the first transparent photographic "film" as we know it today. ♦ The company opened a wholesale office in London, England. 1886 - George Eastman became one of the first American industrialists to employ a full- time research scientist to aid in the commercialization of a flexible, transparent film base. 1888 - The name "Kodak" was born and the KODAK camera was placed on the market, with the slogan, "You press the button - we do the rest." This was the birth of snapshot photography, as millions of amateur picture-takers know it today. 1889 - The first commercial transparent roll film, perfected by Eastman and his research chemist, was put on the market. -

However, some photographers with very high expectancy still use silver halide film. Are they only nostalgic reluctant to technology or is there more than meets the eye? The answer is not so easy if we remark that, at the end of the golden age, films were actually scanned before development. Nowadays film users have adopted digital technology and scan their film to take advantage from digital processing afterwards. Therefore, it is legitimate to evaluate silver halide film “with a digital eye”, with the assumption that processing can be applied as for a digital camera. The article will describe in details the operations we need to consider the film as a RAW digital sensor. In particular, we have to account for the film characteristic curve, the autocorrelation of the noise (related to film grain) and the sampling of the digital sensor (related to Bayer filter array). -

IN the Kodak Medalist You Will Find a Combination of Features Never Before Available in a Roll Film Camera Making a Picture As Large As 2N X 3N Inches
IN the Kodak Medalist you will find a combination of features never before available in a roll film camera making a picture as large as 2n x 3n inches. These features include: • The superb Kodak Ektar Lensj/3'S' with treated inner lens surfaces to give greater clarity and brilliance to pictures. • The accurate Supermatic Shutter with 9 speeds ranging from I second to 1/400 second, plus "bulb" action and a provision for making time exposures. • The lens and shutter mounted in a helical gear focusing tube thus assuring the finest possible hairline focusing. • Prevention of accidental double exposure. • Location of diaphragm and speed controls so that they are accessible and can be read from the top of the camera. This makes it unnecessary to turn the camera over for changing lens opening or speed. • Removable back permitting the use of the Acces sory Back for Sheet Film, Film Packs, and Plates. This back with the Kodak Combination Film and Plate Holder makes possible the use of Kodachrome Professional Film. A film pack adapter makes 12 films available for exposure with a single loading. • Extension units which permit precision copying and close-up photography of small objects without the use of supplementary lenses. ~tc~-de KODAK MEDALIST 1. LOADING The Kodak may be loaded in daylight, but not in direct sunlight. Use Kodak Roll Film 6'20; for the various types of films, see pages 18 and I g. Before loading your camera with film look at the EXPOSURE COUNTER window, to see if "0" is in the forward half of the window; if it is, proceed with the loading as described below.
