  1. Re: Washaid: effective differnce between bisulfite and metabisulfite

    The word I got from ArtCraft Chemicals years ago is that Sodium Bisulfite becomes Sodium Metabisulfite when it hits water. He doesn't carry Sodium Bisulfite because in terms of water-based chemistry...

    In the past, I have stored coated paper for pt/pd prints for several days but in recent years I don't because I've found I get better dMax by humidifying the paper, coating it, letting it dry just...

    IMO, Arista.EDU films are a cost effective way to begin your journey.

    Re: Some JOBO CPA questions

    1- I've never run my CPP-2 so no idea if it would cause any issues; other than, perhaps, an increased strain on the motor as mentioned above.

    2- Algae will definitely grow, but the rate of growth...

    Don't see this tripod name appear very often. I have a Dutch Hill with a Gitzo G1570M head on it that I've used for many, many years for 8x10. Not as sturdy as my Ries A100, IMO, but certainly easier...

    Re: Question using Goerz 19" Artar lens

    I use a 19" Artar of Schneider design on my 8x10 Deardorff. Probably the most important thing to keep in mind is that this is a 480mm lens with its inherent shallower DOF, as mentioned above, and...
  17. Re: “Tripods for Bipods” (John Sexton new tech tip video)

    Same here, John, except mine is a Toho FC-45X and a different albeit similar flyweight tripod. I always figure it's better to be out there with something vs not! ;)

  20. Re: I want to get better at 8x10 scanning, send me your tips!

    I've never used ANR glass for 8x10 scanning, but I've found with other applications that you can see the pattern of the "etching", if you look closely. Funny, too, that I've also still had Newton's...

  23. Re: Anyone have experience using Na2 Pt/Pd and regular Pt/Pd ?

    Not necessarily...you could enlarge a small negative on to Ortho Lith film (creating a positive), then contact print that for a negative to be printed conventionally.
  24. Re: Anyone have experience using Na2 Pt/Pd and regular Pt/Pd ?

    Yes, in an Na2-based process it is used to increase contrast. If you buy pre-mixed, it typically comes in either a 5% or 20% solution. And, yes, it's powerful stuff so you need to be careful. I don't...

    Everything xkaes said, plus sometimes you just need to choose what's in sharp focus and what you're going to let go a little. Stopping down will certainly help, but then you run into diffraction...
  29. Re: Which paper is closest to graded Brilliant (Guillemot version).

    No question that the Brilliant paper changed toward the end. Didn't matter to me because I had an ample stock of the "real" Brilliant in my freezer at the time. I, too, agree with Drew that Ilford WT...
  30. Re: Which paper is closest to graded Brilliant (Guillemot version).

    I would say selenium toned Adox MCC110 would probably come the closet, but that paper hasn't been readily available for quite a while now. Probably the next closest would be Adox Lupex developed in...

    Re: Seeking advice on 120mm lenses

    I know exactly what you mean, John. I've owned and used the 120mm SA for 40 years and it's a favorite! This lens is a "pry from my dead hands" type thing for sure.
