    Re: New Jobo Chemistry Announcement

    The developing agents are CD32 and HQMS. The alkali is sodium carbonate.

    Re: Fomapan 200 pink : fixer change

    Interesting. That seems like a strange recommendation and formulation. The carbonate of course is alkaline. Then when you add the bisulfite (acidic sulfite) the solution will become less alkaline,...

    It’s hard to know exactly what John W. intended although I don’t remember his normal instructions for his pyro developers factoring in a carbonate pre-wash. To be honest it sounds a little strange,...

    Re: Fomapan 200 pink : fixer change

    That’s great news!

    One thing - if by pre-wash you mean before the developer, don’t do that unless you then give the film a thorough plain water wash before the developer. You don’t want any...

    Yes that’s fine. Give the film a few minutes of soak in plain water first to get it throughly re-wet and then do the sulfite bath. 10 minutes in the sulfite with a little agitation here and there is...

    Re: Fomapan 200 pink : fixer change

    The pH of the fixer shouldn’t normally make a big difference, but in some cases residual dyes that have not come out earlier in the process might come out somewhat faster in an alkaline fix, and that...

    Re: Elitist Artist Only? LFPF...

    I don’t know… it seems less “elitist” than it used to be. Of course there also used to be a lot more active members so maybe it just seems less elitist now because there is so little going on.

    Re: Gold Toning

    I think this is correct - ie gold toning on its own will tend to give blue-black tones, and often the blue-black shift will be more pronounced on a warm tone paper than a cold or neutral tone paper....
  13. Re: 8x10 shooters, can HP5 come close to Tri-X 320?

    I think you are right. My guess is the extra low EIs people assign to TXP are primarily a Zone System thing as TXP and HC-110 were a popular combo in the 1970s-80s. Given the shape of TXP’s curve,...
  14. Re: 8x10 shooters, can HP5 come close to Tri-X 320?

    The Tri-X 320 characteristic curve is highly “upswept” with a relatively long toe and very high highlight contrast. It’s a fairly unique film in its tone reproduction compared with pretty much...

    Re: Why TF-5 Fixer??

    You’re probably thinking of Sprint: 247745

    Their fixer is great and they also make the best stop bath in the business (not that stop bath is anything to be pondered over but just saying).

    TF-4 is alkaline. TF-5 is neutral (actually slightly acidic, as are most neutral fixers).

    Re: Why TF-5 Fixer??

    Yeah the slippery feel (vs squeaky) combined with the ammonia odour mean it has become alkaline. The pH of TF-5 should normally be around 6.5 and it should have low odour.

    There’s no major reason to use TF-5 over standard rapid fixers such as Kodak, Ilford etc. The advantages of a neutral pH rapid fixer (Ilford and Kodak are mildly acidic) such as TF-5 are longer shelf...
