Kodak T-Max 100 .
In 1986 Kodak did something remarkable. It released a new kind of film where the crystals lay flat against the film. It’s hard to think of film as a three-dimensional object, but it is. And what Kodak managed to do was produce a series of films that were very sharp with very fine grain. T-Max 100 was one of these films — and the technology was called T-Grain.
What does this mean for photographers? Sharp, clean black and white images with almost invisible grain. If you're shooting architecture, landscapes or studio portraits where detail matters, T-Max 100 is built for that.
It's not a fast film. At ISO 100 you need good light or a tripod. But what you get in return is tonal range — Kodak publishes push processing tables up to three stops so you can rate it higher if the light drops. The latitude is forgiving too, particularly if you overexpose. It rewards careful metering but doesn't punish you for getting it slightly wrong.
Where Tri-X gives you grit and character, T-Max 100 gives you precision. Most photographers end up with both in the fridge. T-Max 100 is also available as Ektapan 100 from Eastman Kodak — same film, same emulsion, different packaging.
- + Landscape and architecture — maximum detail, very fine grain
- + Studio and fine-art portraiture — tonal control, push/pull flexibility
- + Any situation with good light where grain should be minimal
- − Low light without a tripod — ISO 100 needs light
- − Fast action without flash — shutter speed limited by the slow speed
- − Maximum contrast — choose Tri-X 400

T-Max 100 is a very fine grain B&W film. RMS granularity of 8 puts it at the top of the very-fine band, and Kodak describes it as the finest-grain 100-speed black and white film available. In 35mm, you'll see grain in significant enlargements — tight and consistent rather than intrusive — and the film's high resolving power (200 lines/mm at high contrast) means fine subject detail survives. In 120, the grain becomes effectively invisible at most normal print sizes, and the larger negative rewards the format with more captured detail per frame.
The exposure latitude skews toward overexposure: moderately overexposed negatives print well, with better highlight separation, while underexposure is handled but should be avoided. In daylight and controlled indoor light, EI 100 is reliable; for high-contrast scenes such as direct sun and deep shadow, one to two stops of additional exposure at normal development keeps both ends of the tonal range in check.
Push processing is well documented by Kodak: EI 200 and EI 400 deliver results the manufacturer describes as excellent, with EI 800 acceptable depending on scene contrast. Each stop of push brings a contrast increase, some grain increase, and a reduction in shadow detail — modest at one stop, more pronounced at three. Pulling to EI 50 with reduced development is a practical option for high-contrast scenes. At box speed the film carries medium contrast — characteristic curves settle in the CI 0.56–0.65 range at standard development, and the T-GRAIN emulsion produces clean, distinct edges that scan with good separation and minimal fuss in post.
Store unexposed rolls below 24°C in the original sealed packaging. Allow 35mm to reach room temperature before opening — about two to three hours from a standard fridge. 120 rolls warm up faster: roughly one hour from the fridge. Load and unload in subdued light, and process exposed film promptly.
