    Transperency Duplication

    Hi fellow Apuggers

    I need to copy some transperencies and therefore need advice on how to do it. Which method and what equipment to use? Which film?

    I have the following camera systems to use (with a duplicating add-on):

    Canon EOS (EF-lenses)
    Olympus OM
    42 mm Screwmount

    If you've never done this before, you may find it more cost effective to just have a professional lab do the work for you. Depending on the number of dupes you have to make, it may be cheaper and you will likely have perfect dupes as well. The responsibility rests with them to provide you colour matched duplicates.

    In my day, it was Kodak's 5071. It had a lower contrast (and d-max) and you had to spend some time color-balancing it so it was a good idea to buy plenty from the same emulsion batch at a time. This seems to have been replaced by a film called Edupe. Never used it.
    That is called grain. It is supposed to be there.

    Having labs do it in Denmark costs $5 per dub, and I plan to do very many dups, including experiments. So I need some kind of duplicator.

    I have duplicated a lot of 35mm transparencies in the past on Kodak 5071. I used a Contax SLR with a bellows and slide copy attachment, plus the Zeiss 60mm Makro Planar lens. My light source was a enlarger color head. I bought 100 foot rolls of film and bulk loaded (each lot of 5071 needed to be tested in my setup).

    Currently, I just scan the slides (and/or negatives) to a CD. Then I send the CD to a lab for printing to slide film.

    Tom, What resolution do you scan at?
    How are the projected results?

    I don't know what Tom does but I have produced a ton of these things on a Solitaire 16 the res across the long edge should be 4092 for 4k or 8184 for 8k. If you size the slide to 11 x 7.33" then the corresponding res's would be 372 and 744 dpi. Cost for output should be about 5.00 for the first slide and less (much less) for copies.

    When projected 4k looks 'grainy' and 8k looks pretty good.

    Should work fine I suppose, why not?

    The duplicator I had experience was essentially an upsidedown colour enlarger with a holder over the lightsource. A camera was mounted to the column and shot down at/through the slide. Obviously colour balance was controlled, but could also be altered to "correct" off colour work.

    Dupe film, is available in daylight and tungsten. My experience is only with the tungsten film from Agfa. We bought it in bulk rolls and spooled up what we needed to do the job.

    If you have a perfect light source that you can keep even, that lens duper should do the trick. A roll for tests and you're in business...
