About the film

Kodak T-Max 100, code 100TMX, is a continuous-tone panchromatic black-and-white negative rated ISO 100, built on Kodak's T-Grain emulsion.

Kodak's first black-and-white T-Grain films, T-Max 100 and 400, date from c. 1986, the year The New York Times gave for them when it reported the launch of T-Max P3200 in 1988. Kodak positioned it for general photography where the highest image quality and very large enlargements matter, and for copying photographs and photomicrography. In October 1999 Kodak documented it with T-Max 400 and P3200 in one Professional data sheet. A March 2002 notice said those films had been replaced by Kodak Professional T-Max films that needed different development times. Kodak's 2004 sheet explained that production was moving to a more advanced coating facility, with new technology applied to the existing emulsions, which changed processing times slightly but gave the same results. Kodak Alaris's current sheet, of June 2018, still lists the T-Grain emulsion as its first feature. Kodak Alaris lists the film in 135, 120, sheet and long-roll sizes.

The look

Kodak T-Max 100 is a medium-speed panchromatic black-and-white negative with a T-Grain emulsion, made for the finest grain, high sharpness and very large enlargements. It prints on Kodak B&W Print Film 2302 by default, or on a colour print film for a near-neutral image with the print's own tint.

Science & sources

Kodak T-Max 100 calibration chart: OriginalKodak T-Max 100 calibration chart: Processed
Synthetic test chart (skin tones, Munsell greys, colour bars, tone and hue ramps, step wedge, memory-colour roll-off, halation star) before and after the full Ashigrain pipeline: print branch on Kodak B&W Print Film 2302, Super 35 4-perf, default controls, exposure +0.76 stops to match the original's mid-grey, frame 0.

A medium-speed panchromatic black-and-white negative rated at EI 100. Its curve, spectral sensitivity and MTF are digitised from Kodak Alaris's 2018 sheet, and its grain is built from the sheet's single RMS granularity value. The sheet charts no curve at the table's normal development time, so the nearest charted curve is used. It prints on Kodak B&W Print Film 2302 by default.

Response curves and the evidence behind the model

Compare manufacturer data with Ashigrain’s response on the same axes. These curves show how the model is calibrated to its sources; they do not establish a match to photographed film.

Model limits

These images show the film model in use. Spectral response, lighting and viewing conditions include approximations. Halation, bloom, grain size, weave and flicker are not fully measured for each film. The look of real film also depends on development and print timing.

  • Custom lighting spectra, camera metering and the spectral reflectance inferred from fixed-white-balance footage are assumptions used by the model, not measurements of this film.
  • The source gives a daylight exposure index but no colour balance. Daylight calibration and spectrally neutral silver density are assumptions.
  • The source gives only diffuse RMS granularity 8 × 10⁻³ at net density 1.0 (D-76). The response away from that point and the silver-clump size are modelled.
  • No characteristic curve is charted at the table's normal D-76 development of 6½ minutes; the nearest charted curve, 6 minutes, stands in for it.
  • No push curves are used; push and pull use a generic model.
  • The printed MTF rises above 100 %, which the model renders as a development adjacency effect. Its width, amplitude and dependence on density and development are not published and are approximated.
  • The sheet prints reciprocity corrections at a few exposure times; the correction between them is interpolated.
  • The sheet names no antihalation layer; an undercoat is assumed, and the single-layer halation response is not measured.
  • The characteristic response beyond log H −3.15 to 0.65 is extrapolated.
  • In the print branch it prints on Kodak B&W Print Film 2302 by default. Black-and-white print timing is modelled.

Reciprocity: modelled from 1/10000 s to 100 s, following the datasheet's corrections for long and short exposures. Exposure time stops at the ends of that range.
