    I tried looking up this combination on the Massive Humungous Really Really Big
    Development Chart (http://www.digitaltruth.com/devchart.html), but couldn't
    find this combination (they don't list Ilfotec DDX at all).

    However, in so doing I found this little useful bit of information on how to
    tell your Kodak films apart from each other for the perplexed:

  3. The times for old and new T-Max films is very close. For
    instance for both D-76 1:1 and Xtol 1:1 the time for the new
    version is 9.5 minutes @68F and for the old version 10
    minutes, for small tank agitation. I am not sure this would
    make a significant difference. According to one report T-Max
    was always made in the "new" coating plant and really hasn't
    changed. The changes in time are just the variations in
    retesting.

    My time for a normal contrast negative decreased 2 minutes
    with the New TMX. It represents a significant change in CI
    vs. using the old time.

    On average, the difference is a decrease of 1-2 minutes,
    but depends on the developer/dilution. Could vary between
    1/2 to 4 min. less. Never used DDX; suggest you test at
    the old DDX times then 1 and 2 minutes less.

  5. After posting this I looked at some rather old data sheets for
    T-Max. They showed times for D-76 1:1 of 12 minutes @ 68F rather than
    10 min as I stated. I am not sure where I got the 10 minute value,
    probably from an older _Kodak B&W Darkroom Dataguide_. New T-Max shows
    9-1/2 minutes for the same temperature. This is a significant
    difference since a 25% change in time will make about a one paper grade
    change in T-Max contrast.
