    I think I know this one.

    The difference is that the one is the older emulsion and the one is the newer emulsion (akin to TX 400 older versus 400TX newer). Your 320TXP is the newer emulsion and the TXP 320 is the older. Kodak moved their naming conventions to ASA/Name after moving theiir production a few years back. I believe anything with Name - Number is older and anything NumberName is newer.

    I recall seeing similar variations on other films at the Massive Development Chart. I believe they post a variety of times/temps from a number of contributors, who, I assume, have a huge variation in techniques, temps, agitation, enlargers, lenses, cameras, light sources, meters, metering techniques, etc. I take their info, and most other info that doesn't fit my personal conditions and techniques, as a starting point, and not much more. I figure I'm lucky if I get to within +/- 25% of the correct development time with reference material of this nature, but that's almost always much better than starting from nothing.

    Anybody happen to have the Kodak time for TXP320 rollfilm in Xtol 1:1, 20C inversion?
    That is called grain. It is supposed to be there.
