    Re: New Homepage

    Matthias, this is terrific. Some stellar photographs in your portfolios. Inspiring work in a style I like very much, and the uncluttered website is nice to view/navigate.

    Best wishes,

    Michael
  2. Re: John Higbie Invents! Watch This (Pt/Pd laser printer)

    Cool, but unless for some reason someone wants big Platinum prints, I don’t think it offers anything vs either doing it yourself or skipping the whole silly thing and making inkjet prints. Then again...

    Re: Paper developer question

    Most PQ/MQ paper developers are around pH 10.5 and well buffered. Loading them with sodium carbonate is what does this. There are some alternatives but generally thatís how it is done. Borax alone...
  4. Re: Longevity of stock TF-5 Archival Rapid Fix?

    Ron was involved with TF-5 but he didn't write the instructions. The tech sheet is more or less a cut-and-paste from the TF-4 instructions and like most of the Formulary documentation is...

    Drew, good old shuffling in trays? I thought you of all people would have reclaimed whatever custom whiz bang jacketed xenon burst thing they used at JPL back in the day.

    Re: Photo Flo In Presoak OK for PMK?

    There are basically two situations in which pre-soaking is of possible merit. (1) where the film cannot be uniformly wetted with developer in a short amount of time, (2) where film surfaces might...

    Re: Kodak Fixer vs Kodafix

    If you use the "paper dilution" for film, fixing times will be longer and capacity reduced. Note Kodafix is a rapid fixer while Kodak Fixer is not. You'll need to compare the capacity specs at...

  12. Re: Old Distilled Water in Half Empty Bottle...Acidic?

    As far as alkalinity/acidity goes, no problem. Water pH is is a non-issue.
  13. Re: Old Distilled Water in Half Empty Bottle...Acidic?

    It doesn't matter.

    Water has virtually no buffering capacity. For example water might come out of a tap at pH 8 (weakly alkaline) and then fairly quickly go down to pH 6 (weakly acidic) in open...

  15. Re: Issue with Jobo Process operation - Lift arm

    That seems like a good approach to me. I don’t own a machine but I imagine there’s a slight dwell time that makes this fairly easy.

    There’s a new photographers’ machinist guy here who I’m sure could make something but that probably won’t be the cheapest way to go, and as Oren suggests it might just reveal another weak point that...

    Agree with you there. Sounds like a recipe for lost fingers.

  21. Re: Keeping borders square when trimming photos

    I have a Rotatrim for print trimming and it’s fine, but back when I attended workshops with heavy hitters like John Sexton etc. they were using guillotine cutters.

    It’s RotAtrim.

    I’d like to have my own mat cutter one day. I’ve looked into it several times over the years but never pulled the trigger - probably because as I tend to do, I ended up down the rat...

    Re: Brownish Eco Pro B&W paper developer.

    Not really. According to the MSDS it should have a light straw colour. Given the listed ingredients it likely includes Phenidone or more likely a derivative such as Dimezone(-S), the...
  26. Re: Assessing film speed and development time without a darkroom.

    Think of the stouffer steps as neutral density filters you might put on a taking lens. Each density increment of 0.15 reduces the amount of light passed by 1/2 stop of exposure. Those increments...

  31. Re: Assessing film speed and development time without a darkroom.

  32. Re: Assessing film speed and development time without a darkroom.

  33. Re: question re metering for zone III and overexposing HP5+ a little

    You're fine. Setting the meter to 200 gives you a safety factor against underexposure due to the idiosyncrasies of metering, errors etc. No need to make it more complicated.
  34. Re: Assessing film speed and development time without a darkroom.

    You got it. And many (probably most) people at the top of the field do the same.
  35. Re: Assessing film speed and development time without a darkroom.

    That's not a fact. It can be difficult to determine the "right" exposure under tricky conditions. An alternate exposure or bracketing can be worth it. The best photographers I know often make several...
  36. Re: Assessing film speed and development time without a darkroom.

    Agreed.

    Drew mentions having a map instead of flying blind, which of course makes sense, but when it comes to exposure the map is already given to us in the form of ISO speed.

    Cutting ISO...
