Kodak 1934 Elementary Photograohic Chemistry, p.61
Water at 52C 500ml
Metol 2.0 g
Na-Sulphite 100 g
Hydorquinone 5 g
Borax 8.0 g
Boric Acid ncrystal 8.0g
Water to 1l
Dissolve chemicals in the order given.
With a ratio of equal parts of borax and boric acid the development time is unchanged from that of D76. By increasing the quantity of borax with a corresponding decrease in boric acid, the development rate is increased. By decreasing the borax and increasing the boric acid proportionally, the development rate is decreased.
ooze said:This statement has bugged me for a long time. Sometimes I even thought he is taking the piss. However, a while ago I bought a copy of "Darkroom", an out of print book in which, among other photographers, Eugene Smith talks about his darkroom practices. Smith also says that his developer is like D76 but "...with ten times the normal amount of the Kodalk of Borax...". Now, I know that Smith was Ara Guler's most revered photographer, and they may very well have been buddies in Magnum. So he may have gotten this formula from Smith.
36 minutes is an awful long development time for a D76 variant. Maybe he was referring to a divided development and a second bath was a borax solution. I have a reference in my Dignan book where the first developer bath is D76 for roughly half the development time, then a soak in borax to allow the shadows to develop without blowing out the highlights.ooze said:Hi,
When asked about his choice of developer in an interview, Ara Guler (a Turkish photographer who is mostly known for his documentary photographs between 1950-1970) says in loose translation: "...it's like ID-11/D76 but with more Borax. This slows down the development and decreases grain. I develop my film in 36-38 minutes. There is more detail in slowly developed film. If you develop your film in 10 minutes the blacks will be too dark..."

My question is, do you have any experience with such a developer? Does additional Borax indeed decrease grain? Is a dev time of 36 minutes realistic? Does this developer have a name? Any comments are welcome.
Thank you.

But the 36 minute development time, hmm that is really long

When I first used D-76, Kodak's time for Super XX was 17 minutes @ 68 F. Emulsions were much thicker then, which may have been true also of the first Tri-X, and I think part of the thickness was an overcoating. But that was a long time ago.Nick Zentena said:The other question has film changed? On the largeformat.info forum a bunch of film formulas got posted today. D-23 stock with a suggested time of 15-19 minutes. They also call it a soft developer. I use less time then that at 1:3 -)
