  1. Re: FP4 or HP5 in PMK Pyro For Making Platinum/Palladium Prints?

    In general, “universal” developers should produce low fog. The tradeoff might be slightly lower emulsion speed than some dedicated film developers, but this need not necessarily be the case.
  2. Re: Washaid: effective differnce between bisulfite and metabisulfite

    I miss Gerald Koch. He was a nice guy and always a really helpful presence on APUG.
  3. Re: Washaid: effective differnce between bisulfite and metabisulfite

    You can use metabisulfite.

    It’s worth noting the only reason bisulfite or metabisulfite are added is to reduce the pH of the solution to approximately neutral, and the only reason that is done is...
  4. Re: What will happen to your negatives in "the end"?

    I basically agree with Gregg. If I happen to know when I’m relatively near the end of the line, everything in a dumpster.

    Even big name photographers will, or probably should do the same. You made...

    One of my favourite photographers and printers, Mark Citret, has never used anything but Rodinal for his LF film development.

    I’d keep it simple I start and only make it more complicated if required.

    HC-110 is a good choice in a film developer for this since you have it on hand. Rodinal would also work well. Ilford PQ...

  10. Re: Processing 510 Pyro & 100TMX with Jobo CPP-2

    True, we encounter toxic substances all the time, however the dose makes the poison. Pyrogallol is a dangerous compound, and few home-brewers know what they are doing.

    No matter how many revisions they make to the holders, it's simply a fundamental flaw with the entire concept that you can't get around. The best you can do is:

  15. Re: Which paper is closest to graded Brilliant (Guillemot version).

  17. Re: Bergger pancro 400 in bergspeed: Unseen base fog

    Interesting. High fog density could explain two characteristics I’ve seen people attribute to this film. Namely, (1) coarse granularity, (2) low EI.

    Excellent photograph.

    Re: replacement for Moersch Finisher Blue?

    Yes flashing can be tricky when using developer additives, especially finisher blue since PMT is a powerful restrainer that can affect paper speed depending on the quantity used.

    Re: replacement for Moersch Finisher Blue?

    Chester,

    It’s PMT (the primary active ingredient in finisher blue) you need, unfortunately. Benzotriazole doesn’t normally do much of anything to cool the image colour of contemporary papers. I...

    Re: Technique for increasing depth of field

    Not comparable though. Nothing is in sharp focus through a pinhole, and a pinhole is not a way around diffraction.

    Thanks I was wondering if it was around in the early to mid 1980s and it sounds like it was.

    Re: Technique for increasing depth of field

    Cropping also decreases depth of field because in the end depth of field depends on the your chosen circle of confusion, which depends on magnification/viewing distance.

    So… basically the easiest...

    Hmmm. Out of curiosity approximately when was this version of the paper in production?
  31. Re: would flashing help me in this situation?

    Indeed it’s a wonderful film. Wish they still made it in sheets.
  32. Re: would flashing help me in this situation?

    It’s worth noting also that Acros has much higher highlight contrast and densities than say TMX or Delta100. This is one of those double-edged swords. It can make it harder to bring bright highlights...
  33. Re: would flashing help me in this situation?

    This would be the best way - localized (to some extent) flashing. Even using a moving burning card during the flash exposure (as if you were broadly burning in the sky area with a graduated burn)...

    Re: Depth-of-focus problem, enlarging lenses

    I would have thought in the case of an enlarger depth of field is at the negative stage and depth of focus would be at the paper plane.

  40. Re: ABC Pyro in sun hit balcony and Mask for powder water mixing

    Mustafa, that developer is fairly grainy. The reason Weston’s prints have no grain is because they were contact prints. If you are enlarging from 35mm, different story. You may or may not like it.
