'Way back in the mid-1950's Eastman Kodak introduced the first do-it-yourself negative-positive color printing system. Before this time all such work was done strictly in Kodak's photo finishing labs. The paper used to make these prints was named "Type C color print material." Perhaps the "C" stood for chormogenic; I've never seen it officially explained. Anyway, all this was a long time ago (in a galaxy far, far away?). But to this day some folks still refer to prints made from color negatives as "C prints," despite the fact that Kodak dropped the term at least 30 or so years ago, maybe more. Their paper has been called "Ektacolor" since then, and still is. Of course other manufacturers, such as Fuji, Agfa, and Konica have introduced their own brands of chromogenic papers. Someone also asked: "Doesn't Kodak make a high end 25 ISO print film?" Kodak DID make such a film. Originally known as Ektar 25, it ended its days as Royal Gold 25. Same film, new name. It was exceptionally fine-grained, right down there with Kodachrome 25 and Fuji Velvia. 16x20 prints scarcely showed any grain. It was available in 35mm size, and also in 120 rolls as a pro film using the original "Ektar 25" name. Kodak recently dropped these films, claiming that its Royal Gold 100 was so similar as to make marketing both films unnecessary. This is not true. But be of stout heart! Konica has been selling an ISO 50 film for a number of years known as Impresa. It has virtually the same fine grain as RG 25, but with a different color palette. It's available in both 35mm and 120 sizes. Bob Clemens Kodak retiree, class of '89 :-) - Please: Stay on topic. Trim quoted messages. http://www.leben.com/lists for list instructions.
