100TMX vs 100 Delta vs 100 Acros.

  1. Which of these films do you prefer and why?
    Also, what is the optimum developer for maximum resolution and sharpnes
    for these films

  2. I prefer Kodak - I live in the States and want to keep a domestic source of
    extremely high quality materials in business.

    As far as the look of the print - these films are identical IMO. Optimizing
    the lighting, the subject presentation and the point-of-view will improve a
    picture far, far more than changing film. National pride & prejudice aside,
    preference probably has more to do with 'what is your favorite color of
    box'.

  3. are supposed to be for TMax and Delta films. Do they work any bette
    than ID11 or D76

  4. It depends on what you mean by "better." I like Xtol 1+1 on Tmax 400
    because it gives a very straight line, right down into the shadows, and
    I like that. Many people do not like that. I used to use Tmax-RS
    developer on Tmax films because I use mostly 4x5, and Kodak warned about
    possible dichroic fog if you used the normal Tmax developer. I never
    tried the Delta films because I got tired of testing films.

    There is a mis-understanding caused by Kodak's use of
    the T-Max trade name for the developer. When T-Max film was
    being designed the developer used for it was D-76, T-Max
    developer was a later invention. None of the T-grain films
    was designed to need a "special" developer. Developers like
    T-Max, T-Max RS, Microphen, Xtol, DDS, are based on the use
    of Phenidone or one of its cousins as the primary developing
    agent. These developers produces somewhat higher speed and
    somewhat greater maximum density than conventional
    developers using Metol. Of this group Xtol is probably the
    optmimum general purpose developer because it yields
    somewhat finer grain than the others. The T-Max developers,
    DDS (which is very similar) and Microphen seem to be capable
    of slightly higher maximum speed in pushing, but not much.
    The tone rendition of all is very much the same.
    Xtol was designed to meet certain criteria: it is
    relatively environmentally safe since it contains ascorbic
    acid in place of hydroquinone and is easy to mix at room
    temperature. It delivers very fine grain and about maximum
    speed. Kodak seems to have fixed the sudden-death syndrome
    making it a very reliable developer. It is also
    self-replenishing, that is, the developer is also used as a
    replenisher rather than needing a separate solution as for
    D-76. T-Max RS is also a self replenisher (RS means
    Replenishment System).
    In comparison to D-76 all of these developers yield
    about 3/4 stop greater speed, All but Xtol produces slightly
    coarser grain than D-76. Xtol gives slightly finer grain.
    For the very finest grain with the T-grain films use an
    extra-fine-grain developer like Microdol-X (which I think
    has been discontinued) or Ilford Perceptol (which is
    essentially identical). Both when used full strength will
    yeild negatives on any of these films with grain nearly as
    fine as the late, lamented, Technical Pan in Technidol, with
    about 3/4 stop _loss_ of speed over D-76 and normal contrast
    and highlight range. 35mm negatives done this way begin to
    have the smooth tone quality of larger negatives. However,
    the combination produces almost no acutance effect so you
    need really good lenses to get sharp looking images.
    The tabular-grain films do not seem to be at all
    critical of the developer used and will give good results in
    nearly anything but Xtol seems to yield the best combination
    of grain, acutance, tone rendition, and speed.

    Possible Kodak bankruptcy?
