    I just looked at some X-Ray dup film and ZZ Medical warns Kodak is UV sensitive only, but Fuji does not specify.

    I prefer the double-negative technique with ordinary FP4. You make a slightly soft full-scale interpositive first, preferably enlarged, then contact print the new neg
    to working contrast.

    Why slightly soft? How do you achieve the softness, focus?

    I think Drew means low contrast, so that when you go to the enlarged neg one does not lose too much at both ends.

    When I was making negs traditionally I would make a contact or enlargement on scala and process it at Toronto Image works using their Scala Process.
    this cancelled a step and with some trial and error worked flawlessly.

    Wolfgang Moersch has a nice description of the process using Wephota FO5 film: http://www.moersch-photochemie.de/fi...evelopment.pdf
