    Talk about reminiscences....I started out with an old 4x5 view cam myself

    IF you're so nostalgic you should visit Jay Benders site. He sells view cam kits (4x5 and 8x10);

      Thanks for the info, very interesting. When you came home and found that equipment gone I assume that's when "Brian The Terrible" emerged! Wow, that's such a shame.

      It must be sort of a "game" for the lens makers to try to get around the physics of chromatic and spherical aberration. Substituting one substance for another to cancel different errors.

      Don't some digital cameras use processing to account for and cancel some of the inherent errors mentioned above? Of course this is not as good as a great lens, but a well written program could help enormously I would think.

        Well, if you want a reminiscence, my first colour photo was about 1945. Colour film was not available at that time in the UK, and even b/w film was hard to come by (one reason I used glass plates a lot). I took 3 photos of a vase of roses through primary filters onto 2-1/2 x 3-1/2" plates. I then contact-printed them onto some very precious ortho cut film and developed them with mordant-dye coupling and bleached the silver. After drying, I assembled the three films and stapled them. Viewed from a distance of about 1 m, to eliminate parallax, the colours were distinct, although the whole effect was muddy in appearance. Lost at the same time, but the dyes would surely have faded by now, anyway. Shortly thereafter, I started to use Dufaycolor film which re-came onto the market, I think about 1946 or 47. This was a film with a red/green/blue raster printed on the celluloid base with a single pan emulsion. It was, of course, exposed through the base. I had it in a 127 film format and I used it in a Zeca Goldi 16 exp. (3 x 4 cm) camera. Two of these, which I bound in 2" x 2" slide format, have survived. Even today, the colour rendering is superb but, of course, the transparency is poor, as the raster filter, by definition, cuts out at least 2/3 of the transmitted light. If I remember correctly, this film was rated at 12° Scheiner, which would probably be equivalent to something like 10 ASA today. Something like 1/25 sec at f 4.5 in bright sunlight! Indoors, it was an oz of smokeless flash powder (or, it seemed to me, flashless smoke powder!) on a special battery igniter. To quote a song, those were the days, my friends. BTW, I even experimented with the collodion process.

          The technology I can relate to as I have manually produced my own plates just to do it.

          The timing I can't touch. I wasn't even BORN in 1945!

          And I thougt I was an old fart
