    Does anyone have a good starter set of Normal, Plus and Minus times for TMAX 400 Roll Film in HC-110?

    No joy on the Massive Development Chart site?

    Not for plus and minus times.

    Kodak publishes data sheets on their films, Publication F-32 in the case of TMax films. Here's page 13.

    The old adage goes, multiply normal time by 1.4 for a plus development, and divide by 1.4 for a minus time. These would be starting points. But with the normal being 5.5 for TMY at 400, that would yield a too short time for the minus. Perhaps a greater dilution for the minus.

    A year ago, I bought a Hasselblad camera, so I decided to test TMAX400 (120) and HC110 for this camera. These are the results that I found:
    Film: TMAX400.
    EI 250
    Pre-washed: Water, during 1 minute of constant agitation.
    Developer: HC110 (E- 1:47)
    Developed two rolls of film, continuous agitation during the first 30 seconds, and then 3 times each 30 seconds.
    Time of developing: 8 minutes.
    Temperature: 20ªC.
    Stop bath: Tetenal Stop, 1:19, and 1 minute with constant agitation.
    Fixer bath: Tetenal, 1:9, 10 minutes. The first minute with continue agitation, and then 5 times each 30 seconds.
    Results:
    After having taken pictures of a Kodak grey card, I found the following relative densities:
    Zone 8: 1,25
    Zone 5: 0,63
    Zone 1: 0,10
    These densities have been measured with my RH Designs Analyzer Pro. Theoretically, if you work with a condenser enlarger, like my case, a good exposed and developed film should have the following relative densities: ZI: 0.08 - 0.11 / ZV: 0.60 - 0.70 / ZVIII: 1.15 - 1.25.

    Some months ago, I completed this test with the following results:
    N+1:
    Developed: 9.5 minutes.
    Zone 1: 0,10
    Zone 7: 1,25

    N-1:
    Developed: 6.5 minutes
    Zone 1: 0,10
    Zone 9: 1,25

    I hope this information could be useful for you and anybody in this forum.
    Henry.

    This is an excellent combination. I shoot 35mm and 120 TMY at 250 and develop 1:50 from concentrate, 9 minutes @ 68 degrees. For agitation I give three inversions of the tank at the beginning of each minute.

    Henry, I'm a little surprised your Zone 1 density is the same for N-1, N, N+1 rating the film at EI 250 in all cases. TMY is a straight line film with a short toe so Zone 1 tends to move as development times are altered. Just a thought.

    Regards

    For what it's worth----with my tests for TMY and TMX Zone I densities do not change appreciably until the +2 and -2 dev time----in both cases about a 1/3 stop off the measured speed, I'm not surprised at those results. With T-grain film, I consider 1/3 of a stop to be an appreciable difference.

    I do not have a densitometer. I work with the Analyser from RH Designs. Usually, I take different measures of the density in the same negative photo, and I get measures of 0.09 – 0.11 -0.12 – 0.10 for Zone I. They go in this order. For this reason, I say 0.1 is the density in Z1.
    Henry.

    Thanks for the clarification. That makes more sense.
