Kodak T-Max 100

Kodak T-Max 100 is Kodak's fine-grain T-grain B&W film at ISO 100 — the modern alternative to discontinued Plus-X 125 and Kodak's slowest T-grain offering. T-Max 100 was introduced in 1986 alongside T-Max 400, defining the "T-grain" (tabular-grain) category that dominated subsequent B&W film design.

Key features

• ISO 100 rated; very fine T-grain (RMS 8 — among the finest of any current B&W film)
• Cool-neutral palette — distinct from Kodak's warm-leaning cubic-grain films (Tri-X, Plus-X)
• Better reciprocity than cubic-grain films (p ≈ 1.1 vs ~1.3)
• Available in 35mm, 120, 4×5, 8×10 sheet — Kodak's most format-comprehensive B&W
• Compatible with most developers — XTOL (Kodak-recommended), D-76, HC-110, Microphen, T-Max RS

Workflow

• Box-speed development: XTOL stock at 7 min, D-76 1:1 at 10 min, HC-110 Dil B at 5:30
• Push to EI 200 cleanly; EI 400 with moderate grain
• Pull to EI 64 in dilute developer
• T-Max RS is Kodak's matched developer — the cleanest T-Max 100 results

Practical notes

• T-Max 100 is the current Kodak choice for fine-grain landscape, architectural, and portrait B&W work
• The cool-neutral palette differentiates T-Max 100 from cubic-grain alternatives (Plus-X warm, FP4+ slightly cooler than Plus-X but warmer than T-Max)
• Available in all major formats including 4×5 + 8×10 sheet — Kodak's only current sheet B&W along with Tri-X
• Cold storage extends shelf life
