Kodak T-Max 100 is a black and white sheet film in 10.2×12.7 cm (4×5 inch), 10 sheets to the box, ISO 100, standard black and white processing. A panchromatic emulsion on Kodak's patented T-grain.
How the picture looks
Flat, tabular silver crystals absorb light better than cubic ones while barely reading as grain at all. The result is extremely fine grain, high resolution and very good sharpness; in most developers T-Max 100 yields a linear characteristic curve — an even, predictable ramp from shadows to highlights with nothing clipped at either end. That is what makes it a film for big enlargements: the limit on detail is the lens, not the negative.
What to shoot on it
Landscape, architecture, studio and product work, reproduction — anything printed large or scanned at full resolution. The linear curve pays off especially in scanning: the file comes out malleable and needs almost no contrast work.
How to shoot it
Meter at the nominal ISO 100. The film is honest and needs no compensation, but it forgives a gross miss less readily than a classic cubic-grain emulsion — in large format that is a reason to use a meter rather than your eye. Sheet film loads into double-sided holders in complete darkness — a changing bag or a darkroom. One sheet is one frame: exposure is worked out in advance and composition is built on the ground glass. The box holds 10 sheets — roughly €9.63 a frame.
Processing and scanning
Standard black and white developers; the classic partners for T-grain are Kodak Xtol and D-76. Take times from Kodak's datasheet for T-Max 100 or Ektapan PRO 100 — the same film, so the old tables still hold. A rotary processor gives the most even results with sheets.
How it compares
One thing so you do not overpay. The catalogue also carries Kodak Ektapan PRO 100 in this size and these pack sizes — it is THE SAME film under the new name Kodak introduced in 2026. The difference is the price and the printing on the box, so simply take whichever card is cheaper today. Otherwise: Ilford Delta 100 is the other great tabular-grain emulsion, a slightly different tonal signature in the same class; classic FP4+ and Fomapan 100 give a more textured picture for less money.
