Kodak Technical Pan
Technical Pan is an almost panchromatic black-and-white film. This film has fine grain, especially when rated at a low speed, and makes excellent enlargements while preserving fine details. It has the resolution to make 35mm look like 120, 120 look like large format.
While it can reproduce the visible light spectrum, it leans to the red, and so unfiltered outdoor shots render blues, most notably the sky, with additional darkening and reds with some lightening. It was generally used as a very slow film, rated at EI 25 or even 16, although it could be rated at up to EI 320 with a distinct loss of tonal range and a bunching of shadow and highlight detail.
