  1. Re: Midtone Machines - Automatic Film Processing Machine

    What Peter said. A key point about the 3004/3005/3006/3010 drums is that the "wells" in which the film is inserted are not strictly cylinders - they are slightly barrel-shaped. The structure of...
  2. Re: Midtone Machines - Automatic Film Processing Machine

    To be clear to those who are not familiar with the Jobo processors, the processor needs an after-wash only if you don't do the film wash on the processor. If you do, that takes care of both the film...

    Re: questions about caltar ii-n lenses

    We're still left with the mystery of why some of the late-production Caltar-labeled Grandagon-N's have green rings while others don't. But this is entirely a bit of academic trivia - it's completely...

    Re: questions about caltar ii-n lenses

    Bob, Caltar II-N plasmats with serial numbers from the Apo-Sironar-N era have the newer typeface but not the silver ring. At least that's true of the ones I own (150 mm and 300 mm), and I can't...

    Re: questions about caltar ii-n lenses

    For normal plasmats, Caltar II-N is Sironar-N or Apo-Sironar-N, depending on the production date. (Wide-angle Caltar II-N's are Grandagon-N's.)

    I've never seen a Caltar II-N in the 360mm focal...

    Re: Fastest film for 8x10 other than TMY

    OK. Beyond HP5 Plus, TMY and TXP, I think the other options are Foma 400, Foma Retro 320 and Bergger 400. Afraid I've not tested any of those, but between HP5 Plus and TXP, I'd certainly select HP5...

    Re: Retain highlights with Tmax 100

    Unlike TMY, TMX curve shape is highly dependent on developer choice. In diluted XTOL or D-76 it starts to shoulder far, far before 20 stops.

  37. Re: Camera scanning: conservator's perspective

    No. You are correct about the fact that we're discussing grain clumps, but you are way underestimating the resolution required to accurately "describe" film grain. 6,000 ppi gets you in the...
  38. Re: Camera scanning: conservator's perspective

    These standards are inadequate if one seeks to preserve the grain structure of the film. In fact, for ISO 320/400 films like Tri-X, 4000 ppi will produce aliased pseudograin which increases the...
