    I have a couple of boxes of Kodalith 2556, type 3 that I got in a job lot free when I purchased my enlarger.

    I would like to give this a try and eventually make a negative that I can use for contacting (8x10) silver prints. I have an image in mind which is from a colour neg (c41) but I reckon I am going to run into sensitivity issues due to the colour base of the colour film. Am I correct or can I compensate by extending exposure time?

    Another question is that the film is 15 years out of date and I have no idea how it has been stored. Should it be useable? I will try it anyway but wonder if anyone has used this stuff so far out of date?

    I very much doubt that you will make a good negative on a Ortho film from a color original. If you can get some 8x10 Tech Pan or any other 8x10 film you should be way further ahead and save yourself much aggrivation.

    Thanks Claire for the quick response.

    Trouble is if I buy 8x10 film I will want a camera to go with it :smile:

    And what's wron with wanting an 8X10 camera? :smile:

    hehehehe

    FWIW - I have some VPS-III that expired in November 1988 (frozen since new). It works just fine, but YMMV.

    Kodalith, unless subjected to high temperature and humidity, will last a very long time. I have made negatives from 35mm color slides on it but one must remember that Kodalith is an extreme contrast film, not intended for pictorial use. Little or no gray tones. It is possible to get a continuous tone negative out of it using highly dilute D-76 (1:9) or Technidol. Chances are it will still be rather high contrast, though. Kodalith is fun stuff to experiment with. Expose it at ISO 6 or, under the enlarger, at paper speed. Try it. Play with it and have some fun.

    I doubt that you can come up with a useable negative from an ortho film. I would think that it would require some fairly extensive filtering plus a developer that would be capable of providing a continuous tone negative from a high contrast material.

    What came to mind, for me, is that if you could come up with a copy of Kodak's Creative Darkroom Techniques, in it there are a variety of very creative uses of Kodalith. Some involve color separations to arrive at posterizations among other types of prints. Very original...very unique.

    The first thing that I would determine is how high the FB+fog is on this fifteen year old film.
