John Sexton was indeed using D76 for the new Tmax400. Here's an excerpt from his October 2007 newsletter, where he first talked about the film. (Note that he tested 120 rollfilm, not his usual 4x5 sheets.) "I have been processing the new T-MAX 400 120 film in D-76 1+1 for 7 minutes at 68F with manual agitation for 5 seconds every 30 seconds for normal development. I have been using an EI of 250 with the new emulsion, just as I did with its predecessor. This procedure has produced negatives of excellent quality for enlarging with a diffusion light source. The grain structure has smoothness that to my eye I have never experienced with a film of this speed." Hope this helps! -Charlie Dennis Purdy <dlp4777@xxxxxxxxxxxxx> wrote: I shouldn't have said I "knew" he tested it with D76, I should have said I was told by someone who said they knew. But this is the internet and who knows what is true. I have on pretty good authority that Kodak considers D76 the standard to judge tests by.
