    Y'all are having too much fun to be bothered. If you look at Lefkowitz, you might also want to look at:

    Gibson, H. Lou. Close-Up Photography and Photomacrography. 1970. Publication N-16. Eastman Kodak Co. Rochester, NY. 98+95+6 pp. The two sections were published separately as Kodak Publications N-12A and N-12B respectively. Republished in 1977 with changes and without the 6 page analytic supplement, which was published separately as Kodak Publication N-15. 1977 edition is ISBN 0-87985-206-2.

    Gibson is very strong on lighting, exposure, and on what can and cannot be accomplished. His books, although relatively weak on getting the magnification with lenses made for modern SLR cameras, provide a very useful foundation for thinking about working at magnifications above 1:10 and especially above 1:1. Extensive bibliography.

    H. Lou Gibson is one of the Englishmen that Kingslake brought to EKCo. He's best known for IR photography. His Photomacrography pamphlet is the most frightening photography book I've ever read.

    Dan, thanks for reminding me. I see I have that 1977 Kodak publication which is quite good but with some weaknesses, as you point out.

    Another useful Kodak publication was their "Photography Through the Microscope", ISBN 0-87985-019-1, 1974. It of course deals with high magnification and is pretty informative about some sophisticated techniques such as interference contrast and the Nomarski version of such.

    Re: Making a scanner with a DSLR

    Can any of you recommend a good lightbox for shooting negs with my 5D. My Bretford Acculight has hot spots....there must be something better out there and I don't have any local shops so I need to mail order.

    Thanks,

    Serge

    You might try modifying your box a bit. For instance, you could get some white foam core. Make a flat-topped pyramid, with the bigger opening sized to fit over your light source. At the smaller end, put a piece of diffused plexiglas. You will lose light, of course, but you should be able to make a pretty even source.

    That would take a lot of belt length, much more so than with other systems. That concerns me. Bottom line is we won't know until you try it : ). Could just work.
