  1. Re: Precision and Accuracy in LF Photography: How much is enough?

    @jp I like the precision/accuracy scale. The one with no precision and no accuracy should have fewer marks on the target though (because some will miss the entire dartboard).

    I see I fall into the...

    Just don't use those orange capacitors that Nakamichi used in their cassette decks. Use the capacitors that EG&G used in their sensitometers.

    Re: Developing Tri X 320 (4x5) in D76 1:1

    I made the same mistake Stearman. Anyway develop it more than 9 but less than 13:30 (I develop all my film too long compared to most other people) and you'll be fine.

    Re: Developing Tri X 320 (4x5) in D76 1:1

    13:30 is my standard time for Kodak's film in D-76 1:1 at 20C, it gives me an aim contrast of 0.62 (ASA parameters).

  15. Re: Calibrating a Zone VI compensating developer timer

    Note for future reference: Picker writes about the compensating timer in newsletter number 41 December, 1984

    Should be good for all film, all paper. The paper curve is steeper than the film curve.
  16. Re: Calibrating a Zone VI compensating developer timer

    Even without tests the standard calibration should match. I think film is calibrated to Tri-X. So your results should match the time/temperature chart for Tri-X
