Kodak Ektapan 100 is a 135 black and white negative film, 36 exposures, ISO 100. It belongs to the Ektapan family, built on T-grain: flat, tabular silver halide crystals that absorb light better while staying inconspicuous.
How the picture looks
T-grain gives a clean image with high resolution and sharpness — higher than traditional cubic-grain emulsions. Contrast is high, edges are distinct, grain texture is largely absent. The maker states Ektapan 100 as the sharpest and finest-grained film of its speed.
What to shoot on it
ISO 100 means daylight, and a tripod at dusk. The film is built to take a big enlargement, so it earns its place where the frame is going to be printed large: landscape, architecture, studio, street on a sunny day.
How to shoot it
Meter at box speed. The Ektapan family has wide exposure latitude, so push and pull both work — the maker says so directly. But T-grain is less forgiving of sloppy development than a classic emulsion: hold time and temperature exactly.
Processing and scanning
Standard black and white processing. Tabular-grain films scan well — that is their strength: a clean, low-noise image with no need to dig detail out of grain.
How it compares
The direct comparison is other tabular-grain films of the same speed. A classic cubic ISO 100 will give a different, more "filmic" character with visible texture; Ektapan 100 goes the other way, as smooth as it gets.
