Barleben Jr., F.R.P.S., priced at 50 cents, copyright 1933, 3rd edition published in 1934, by the Fomo Publishing Company, Canton Ohio? It's a handy little thing, 5 by 7 inches in size, which Mr. Barleben says in his introduction is really a reprinting of a looseleaf binder of material he had put together and decided others might like it. It has lens, exposure, projection, film, filter, developing data and conversion factors for a variety of weights and measures, some nifty cut-away pictures of lenses and a double-truck ad in the center from the E. Leitz company , maker of the Leica Autofocal Camera, models D E and F. Looks like a predecessor to the Leica Manual, and I wonder if anyone knows if there is a connection? how's this for weird: under "projection data" it talks about the Udimo projector that uses leica camera lenses, and tells you which one to use for various screen sizes and distances. A 50mm elmar at 6 feet gives you a 2foot, 6 inch by 3foot 9 inch image, it says here. For longer distances it suggests longer lenses. anyone know anything about it? charlie trentelman ogden utah - -- To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html
