The stuff I used was about 15 years old when I employed it in mived developers, something like 125g Sulfite, 250 g Carbonate and 25-50 g Blycin for a stock solution. I think it was diluted 1:3 or 1:7 for working strength. It was alright, nothing special. Well, the working solution never seemed to go bad, just got used up. I tried the formula in the Ilford patent where they got some superadditivity between Phenidone and Glycin. That one looked like ID-11, sort of. It was nice. Later, when I got a nearly real darkroom, I started experimenting with a lot of stuff, and began to rely on percentage solutions. That's when I did the Lye/Bisulfite trick such as you di with Carbonate. I was now using 30 something year old dark brown stuff; the same stuff I bought when a teenager. The stuff sizzled going into the Lye and the solution cleared after the Bisufite. It worked for about 5 years, perfectly. Recently, I came across a bottle that had been used, about 60% left. It was still clear. I had to chuck it because of packing for a move. I still have a few experiments to complete, and I just ran across the original container, half full with dark Brown Glycin powder. Dare I? Regards, John S. Douglas, Photographer - http://www.puresilver.org Please remove the "_" when replying via email Robert Vervoordt, MFA |

Of course it is an agent with a tendency to "smooth" out those Silver grains by solvent action in some developers, but is that always so? There are a number of formulae with low solvent action incorporating Glycin. Perhaps this "solvent" reputation is not so deserved. Robert Vervoordt, MFA It's not the case. Most of the "fine grain" formulas used PPD along with glycin. Right, along with a truckload of Sulfite. Look at the 777 formulations. Metol, Sulfite Glycin and PPD. It's good stuff. Lasts forever, too. BTW, my promising experiments were with Glycin, Phenidone and color developing agents. Just updated Sease variants. There was a speed increase, so that's why I want to get back to them. Cheers. Robert Vervoordt, MFA |

ok friends, I always develop in dektol but this is a time that I use a massive develop soup. I was searching for more economy developer, I was thinking about agfa Neutol. Anyone has tryed this developer (sounds good)? Any other suggestions for more economy in developer? lookin for suggestions!! Stefano Ciao Stefano, Many mentioned the fact you can mix your own. Although I've everything needed to do it (chemicals, balance, ...), I do it only for special products and very simple ones (stop bath, wash aid) which are usually overpriced. For standard print developer and fixer, I found Agfa has very good quality/price here in Europe. I use Neutol NE liquid (neutral tone, very similar to Dektol) and Agefix. Both are liquid so you can mix them very quickly. Prices in France (http://www.prophot.fr or http://www.nighlight.fr) are 5.50 Euros (1.25 liters bottle, without VAT) and 3.60 Euros for the fixer (1 liter pack, without VAT). You can check also with german distributor who should have similar or perhaps lower prices. Neutol exists also in warmtone and several other packages (I think powder is also available). Just a word about Agfa, the new entity has opened its website: http://www.agfaphoto.com You can see the administrators are also among the serious shareholders ....

Dan Quinn wrote: stefano bramato wrote Any other suggestions for more economy in developer? I will add a little more to my post of 10/13. Using the least fluid practicle, lfp, you can use the developer and fixer one-shot. Determine the amount of Neutol needed to fully develop one sheet of paper. Use no more than that, then discard. All you need is enough fluid to cover the paper. You can also do this with dektol, which I conserve by mixing the least I need to cover paper at 1:2 or 1:3. You can use highly dilute paper developers (dektol can be used at 1:8 so if you develop only 2-3 8x10s you can use 1 oz dektol + 8 ounces of water.) The only drawback to this is that while you just need to extend the developing times to develop to completion, at higher dilutions maximum blacks (the D-max of the paper) will be less than if used at standard dilutions. Haven't used Neutol though. Do the same with the fixer. I think you will find that you do not need a stop bath. Only one tray is needed to develop and fix. No tired developer, and no tired fixer.

Where does one find this chemical, as well as other photo chemicals? There is more than one good source. I favor Photographer's Formulary because they supply a very large selection of chemicals and they do so sell each in small to large amounts. There are five essential chemicals for film and paper developing. The five are; metol, sodium sulfite, sodium carbonate, sodium or potassium bromide, and sodium or ammonium thiosulfate. For those new to Homebrew I suggest these quantities in the above order; 100 grams, 1 lb, 1 lb, 100 grams, and 1 lb of the sodium. I suggest sodium thiosulfate anhydrous because it does not spoil and is easy to mix fresh when ready to use. Dan |
