Thank you to those who replied to my last thread, and as a result of that, I mixed up D-76d from raw chemistry and developed Tri-X with it, and I am going to try D-23 next. I haven't printed them yet, but the negs look good. This new post is on a similar theme and for anyone who has seen Sebastiao Salgado's amazing prints from 35mm Tri-X with his project 'Workers' and 'Migrations', this thread may interest you. He has fantastic printers who manage to extract shades of grey any lesser printer couldn't, so I don't think it is all to do with what film developer is used. However the developer that was used has always interested me.
I found this interview on the internet with Salgado, about his use, or his lab's use, of D-76 during his days of using film, mostly Tri-X but some P-3200 too. It is scant on detail, and his English isn't always the best, but from what he says here, his lab modified the formula of
D-76. He says:
"When I used films, it was necessary to produce a special developer for the films as I exposed them in a very special way. I always overexposed my negative and underdeveloped the film to have a negative very gray, to have all the details in the shadow. I photographed a lot against the light, and I have a lot of shadow areas. To have the data inside the shadow area, it was necessary to do a special development, and I used one Kodak developer called D-76. However, I made the developer myself and modified the formula of D-76 to have a different kind of negative - much grayer negative".
I can't believe he literally 'made the developer' himself, I think he means it was a bespoke developer made for him, but in any case, what do you think this 'special developer' could have been? How would modifying the formula of D-76 give 'more greys'??!! Is he talking about divided D-76 perhaps? Any thoughts?
Like Bill Burk said, a lot of people make their own D-76. Kodak published the formula for it soon after they introduced it. Back then, most serious photographers preferred to mix their own chemicals, even if they were using formulas invented by chemists at big manufacturers like Kodak. Kodak made money anyway because they were a major maker of the various chemicals used to make developers. It was common in the past for camera stores to stock jars of metol, hydroquinone, sodium sulfite, etc. for those who wanted to mix their own. There are still those who do this, and over the years a number of alternative D-76 formulas have been created and published both by Kodak and by photographers. Companies like Photographers Formulary sell the raw chemicals needed for DIY chemical mixing.
I don't know what Salgado uses. He may have modified the standard D-76 in some way, or he may be using one of the many alternative formulas that have been created since the original D-76 was introduced in 1927.
I understand his developer of choice was ATM49 now sold as ADOX 49.
Agfa Atomal and May & Baker Promicrol used the same developing agent 2 (beta-hydroxyethyl) aminophenol sulphate, which was manufactured in Russia for use in a non photographic process, when that process ceased it was no longer financially viable to manufacture. Both developers were reformulated.
Both developers have similar properties, finer grain than D76 and no speed loss. I did use Promicrol around 1970.

I think the ATM 49 relates to the period he switched to medium format for the Genesis project before he switched to digital.I understand his developer of choice was ATM49 now sold as ADOX 49
It’s important info that he overexposes and underdevelops. That helps me understand his rich grays.
I don’t know what constituents he alters but many people mix their own D-76.
If Salgado explains more, I would be interested to know.
Seems he is exposing for the shadow details, what Ansel Adams called N+, that sets the shadow at zone II or III, then reduces development time so as not to blow out the highlights zone VII. Without additional information it is difficult to know. In this case D76 works just as well as others who use the Zone System.. AA used D23, Edwal FG7 (long gone) a number of Ansco developers, and later in life HC 110. Those who follow Phil Davis Beyond the Zone System use a number of low contrast developers including one developed by Davis for Tmax 100. TirX is a very forgiving film, works well with high contrast scenes as does Tmax 400. I have used several divided developers over the years, Diafine, divided D76, Berry Thornton's version, in my experience if using a divided developer expose for Zone III, then follow directions, usually 3 to 4 mints in part A and part B. Salgado might also split print.
Yes occasionally in the past with Tri-x and Emofin, but I suspect I was trying to develop too many films with one batch of developer. Never with Barry Thornton's two-bath and Ilford films.Did you ever get the problem with bromide drag/streaking with divided developers? I tried Tetenal Emofin, and Divided D-76 and Diafine and all of them gave bromide drag after the first use, this was for 35mm Tri-X. I gave up with divided devs after that!
Basically he found an EI and development time for a particular film, in a modified developer. Like most of us. I'm sure his choice is EI and development time had more of an effect than modifying the developer...
Surely we also need to know how he metered the scene, especially shooting against the light?
I suspect his idiomatic English makes that description above seem a little mysterious, but without a clearer description there's no guarantee that he approached everything in a logical way.
Results are good, though, I grant you.

N+1 in the classic Zone System is developing more than "normal" (not less, as Salgado does). It has nothing to do with exposure. In the Zone System, exposure is based on a shadow value. Salgado likely used an in-camera meter or some other kind of averaging meter. "Overexposing" with such a meter in contrasty situations compensates for the meter's tendency to underexpose in such situations, in essence getting the shadow exposure close to where a Zone System practitioner would have placed it in the first place.Surely we also need to know how he metered the scene, especially shooting against the light?

When did the reformulation take place? I guess Salgado already used the "newer" version.

I don't doubt for a moment that Salgado's printers use more than one grade on a print, they also selectively bleached areas of the print to bring out detail in the shadows.
