Spent 24 years doing various things photographic for the Air Force, including a teaching stint and some time with the SR-71. Currently working on a book on the early history of the 16mm film format and equipment, as well as a compilation and index of the Kodascope Library Catalogs from 1920's and early 30's. My daughter says I'm the only person she knows who reads math books for entertainment. Not quite an accurate assessment, but close enough. Collector of photographica for 50 years. Dip and dunk photographer, and if preferences counted for anything, wouldn't have anything smaller than a 4x5 in hand, but my darkroom (alas) is now in storage. Digital imaging has its place and its techniques, but it is no more photography than watercolor is oil painting.
