  1. 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...
  2. 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.

    Makes sense to me. Like I said, Ron didn’t write the stuff on the PF site for TF-5.

    Re: TF-4 User For Years...Want To Try TF-5

    It was Wimberley who started the revival in the late 1970s. Also Hutchings used regular mildly acidic Kodak fixers. In any case it doesn’t matter. If you like TF-4 there is no reason not to use it....

    Hi Doremus, unfortunately the tech sheets for both TF-4 and TF-5 (like many PF products) are mostly marketing/hyperbole so there is not a great deal of information. The instructions for both indicate...

    Re: TF-4 User For Years...Want To Try TF-5

    Sea water does make a good wash medium (it’s like a weak hypo clearing agent), and can even be a very very very slow fixer mostly for silver chloride emulsions so yeah sea water is pretty neat.

    The pH of your water is irrelevant. Water has essentially no buffering capacity so its pH is totally overwhelmed by the chemicals you add to it. Furthermore imagewise stain from pyrogallol or...

    Re: TF-4 User For Years...Want To Try TF-5

    I was referring to imagewise stain from pyrogallol or catechol developers, which OP referred to. Regarding anti-halation dyes/TMax and fixers, bogus. But use whatever you want. They all do the job.

    They will fix the same and wash the same. Neither will have any affect on imagewise stain (nor will any other non-hardening rapid fixer). TF-5 is neutral rather than alkaline so less odour than TF-4....

  14. Re: How to finish, wash and dry fibre paper prints for exhibition and sale

    I hate to bring this up, but realistically does anyone here need to worry that dry-mounting is the reason museums are not acquiring their prints?
  15. Re: How to finish, wash and dry fibre paper prints for exhibition and sale

    George Tice does something similar. The print is dry-mounted to paper which is then affixed to the mounting board.
  16. Re: How to finish, wash and dry fibre paper prints for exhibition and sale
