jim_appleyard Posted January 25, 2004 Share Posted January 25, 2004 While surfing this wonderful site I happened across a question from 2002 about the formula for Acufine. I doubt that the exact formula has ever been published, but I do have a 1984 issue of Photographic in which Paul Farber (the guy was great for this stuff) gives his own version: Water @ 125 degrees 2.5 cups Phenidone 1/8 tsp. Sod. sulfite 7 tsp Hydroquinone 1.5 tsp Borax 0.5 tsp Sod. Carb. 3/8 tsp Pot. Bro. 1/8 tsp Water to make 1 qt. The type of Sod. carb is not given, but I would guess it's anhydrous. You guys DO have teaspoons hanging around, right??? Link to comment Share on other sites More sharing options...
jorge_oliveira2 Posted January 26, 2004 Share Posted January 26, 2004 Since tesaspoons are not the same all over the world (rounded): Water 750cc; sulfite 54g; hidroquinone 4.5g; phenidone 0.25g; borax 2.5g; sod. carbonate 2.25g; pot. bromide 0.8g; water to 1 liter. (I did not do the conversion, it's in R.P.D and I feel the mixing order above is 'more correct'). Just a note - I've seen comments that Acufine is a 3 active ingredients dev (P,Q and some other). Any comments on that? Link to comment Share on other sites More sharing options...
hans_beckert Posted January 26, 2004 Share Posted January 26, 2004 You may want to try ID-68 by Ilford. http://www.pofig.net/photodb/viewChemistries.do;jsessionid=904B82625A01F83ADA6A756D3455AB0F?action=Details&id=10 Name: Ilford ID-68 Category: Film Developers Formulation: Water 750.0 ml Sodium sulfite (anhydr) 85.0 g Hydroquinone 5.0 g Borax (decahydrate) 7.0 g Boric acid (crystals) 2.0 g Potassium bromide 1.0 g Phenidone 0.13 g Water to 1,000.0 ml Comment: Fine grain borax developer. This formula is apparently a phenidone version of buffered D 76 and is equivalent to Microphen or Bromophen. Use as for Microphen. Link to comment Share on other sites More sharing options...
