warm tone paper developer

[Phillip P. Dimor]

I like Ethol LPD, 1:4 to 1:6 is warm. 1:1 is blue black. Although i'd love to try another real warm-tone developer, ethol lpd keeps forever.

Alexis,

I'm fairly sure Freestyle is selling Neutol, as they've picked up the other Agfa chems out there. Might want to give them a look-see.

Will be shipping back chems, papers, films from Germany later this year.

Well it isn't listed in their catalog...at least the online version. Just got in an order and I'll see if they sent a hardcopy, then check in it.

I mix my own Defender D-55 or Ansco 130 for printing with Forte PWT. The D-55 is a very clean developer, producing a good tonal range. However the Forte suffers the greenish cast in it. The Ansco is also very good, but expensive and the glycin can be somewhat tougher to dissolve. Since I tone all prints in Nelsons Gold Toner, the cast has not been a problem. However, I was wondering if the formulas for the Edwal, or Zonal Pro were available anywhere? I don't usually buy any chemistry off the shelf anymore, prefering to mix and tweak my own.

Ansco 130 is worth trying because it has a very long tray life, something you mentioned as being important. I've not yet tried it with Forte papers (although I will soon), it is a beautiful developer with the Ilford and Agfa papers with which I've used it. Greater dilution results in softer contrast and a warmer tone.

Any information on substituding Sodium Carbonate for the Potassium Carbonate? I'm thinking the sodium compound would be very similar, but would require a different dilution. I've got a lot of it here and could compare the developer against the original D-55 and the Ansco 135 formula. The 135 does a nice job with Forte papers and doesn't produce the green cast.

Potassium salts are said to give warmer tones.

The MWs are:

Na2CO3anhyd 106.0
Na2CO3mono 124.0
K2CO3 138.2

So if a recipe calls for potassium carbonate 200g and you have sodium carbonate anhydrous, the eqivalent amount of the latter is:

200 x 106/138.2 = 153g

But the result is likely to be different because the potassium carbonate was probably chosen to make the image warmer.

Try the APUG Chemical Recipes

55 D (there was a url link here which no longer exists)

Thanks Tom:

But I own the cookbooks. I've got quite a bit, except of course the modified 55D. Guess I'll have to include some K Carbonate in my next formulary order.

Don, Sodium Carbonate will work ok in 55 D but Potassium Carbonate is more soluble.
