Kodak T-MAX 3200 (TMZ)

The name has always been misleading. Kodak's native speed for T-MAX 3200 TMZ was rated internally closer to EI 800. Kodak shipped it at 3200 because that is where photographers pushed it. The T-grain technology meant it held together at those push speeds better than any conventional-grain emulsion of the time, and the grain structure at EI 3200 in D-76 or T-MAX RS was finer than Tri-X pushed two stops to 1600. That was the actual value proposition.

The original TMZ-coded emulsion ran from 1988 until Kodak quietly discontinued it in 2012 during their bankruptcy reorganization. When it came back in 2018 as P3200 (the P standing for push), the emulsion was reformulated. The new version is slightly different in grain character and shadow rendering. Shooters who used the original heavily have opinions about the difference; most people who pick it up now have nothing to compare it against.

Prince's concert photographers used it. Sports photographers working under arena lighting used it. Photojournalists covering night riots without flash used it. Any situation where you needed film speed more than anything else.

Development time matters enormously with this stock. Push to EI 3200 in T-MAX RS at the recommended time and you get workable shadows. Overdevelop by two minutes and the highlights block up badly. The film rewards accurate development more than most.

The reciprocity exponent is 1.04. This is one of the most favorable reciprocity characteristics of any film, which makes sense given the stock was engineered for low-light short exposures. Zone Light Meter applies the correction past one second. Long exposures on a film designed for fast available-light work are uncommon, but if you are shooting predawn exterior work, the math holds.
