Tmax & D-76
Well, the results of my first use of Tmax 100 are in here at Nebenzahl
Laboratories, GmbH, and I can tell you that I'm very happy with them. I developed it in D-76, 1:1 dilution, using rather old (~5 years) stock, and the negatives came out looking gorgeous. The prints, too. (This was 35mm film. I'd really like to shoot something larger in this film stock someday.) There may be better developers for Tmax; the consensus seems to be that Xtol is the best stuff to use. But while this combination may not be the ultimate, D-76 certainly does a quite credible and creditable job with this film. I only wish I had a better scanner so I could post pictures that would do the prints justice. -- The fashion in killing has an insouciant, flirty style this spring, with the flaunting of well-defined muscle, wrapped in flags. - Comment from an article on Antiwar.com (http://antiwar.com) |

That combination has grain nearly as fine as the late, lamented, Technical Pan but with much greater speed (about EI 50) and much more easily controlled contrast. So do you use D-76 full strength or diluted 1:1? I have some Microdol-X, so I'll use it on my next roll of T-Max. A one-stop loss of speed is no big deal. -- The fashion in killing has an insouciant, flirty style this spring, with the flaunting of well-defined muscle, wrapped in flags. - Comment from an article on Antiwar.com (http://antiwar.com) |

My favorite with TMax 100 is Rodinal 1:50 for about 11 minutes at 68 degrees fahenheit. Full agitation first 30 seconds, then for 5 seconds out of each 30 seconds thereafter. Beautiful negatives. |

I usually use D-76 diluted 1:1 as a one-shot. For a time I was using it full strength and replenishing but I found I was not developing enough film to justify that and I also prefer the somewhat longer developing times the diluted developer gives. Microdol-X and Perceptol, which are essentially identical, lose their extra-fine-grain property when diluted so must be used full strength is minimum grain is the objective. At 1:3 they produce full film speed and begin to show some acutance effect but the grain is then about the same as D-76. -- -- Richard Knoppow Los Angeles, CA, USA |

Some photographers on the apug forum reckon that D-76 gives great results with the latest T-Max 400 (2-TMY) film. I use D-76/ID-11 for all of my film developing and it's still a great film developer. |

There's Ilford Perceptol which is a good substitute and also Rollei Low-Speed developer which is a similar type of developer to Mic-X and Perceptol, but sold as a liquid concentrate. http://www.imx.nl/photo/Film/page123/page123.html |

Lindan, Cleveland, Ohio Darkroom Automation: F-Stop Timers, Enlarging Meters http://www.darkroomautomation.com/da-main.htm n o lindan at ix dot netcom dot comThe trouble with that is, what to use when the Mic-X supply runs out?

As far as I can tell Perceptol and Microdol-X are identical. The differences in developing times given for them for some films is probably because of a difference in the contrast index being used for the testing. In both developers the fine grain agent is sodium chloride. Both developers have an extra-fine-grain property when used full strength but loose it when diluted. There is a speed loss of about 3/4 stop when used full strength but when diluted 1:3 the speed is about the same as in D-76, however, the grain is also comparable then. Both are acutance developers when diluted. The line about T-Max being as fine grained in Microdol-X as Technical Pan in Technidol is from me. I've used T-Max 100 in Perceptol and Microdol-X full strength. Speed about EI-50. The results were very fine grain and had the smoothness I would normally associate with a larger negative. The combination is much easier to handle than Technical Pan was since the contrast does not become excessive so easily. I found that Technical Pan in Technidol had to be shot at about EI-12 to avoid excessive contrast and difficult to print negatives. A caution: the combination had virtually no acutance effect so images may appear to be somewhat blurry unless your lenses are outstanding. I am, of course, talking about 35mm. For 2-1/4 x 2-1/4 the difference is not so great although it will help if you make very large prints. As far as overall performance it depends on what you want. For general use D-76 either full strength or 1:1 works fine for T-Max films and is probably what was used during the research period. Xtol is the optimum developer yielding slightly higher speed and slightly finer grain than D-76 and not producing a shoulder until very high densities are reached. T-Max RS also yields somewhat higher speed but I've found it to be slightly grainier than D-76. Both T-Max RS and Xtol are excellent for pushing. Tone rendition is similar for all although there are some differences in the shape of the published curves. For the most part the curve shape of a film is determined by the emulsion and is varied only a little by development. However, it may be enough to make a noticable difference and after that its a matter of taste. -- -- Richard Knoppow Los Angeles, CA, USA |

Grain is amazingly fine, actual resolution is very good, but it just didn't look /sharp/. Xtol (1:1) gave me much sharper looking results than Microdol-X at full strength. I somewhat puzzled at how obvious the effect seemed; everything I think I know tells me to expect more subtle differences. And yet "appear to be somewhat blurry" only seems a slight exaggeration of my disappointment with TMX in Microdol-X. Peter. -- |
