Profile notes
Fomapan 400 Action (ISO 400/27°) is a panchromatically sensitized black-and-white negative film manufactured by Foma Bohemia, designed for shooting in low-light and fast-action scenarios. The emulsion features a tabular grain structure with RMS granularity of approximately 17.5, giving it a noticeably grittier character than Fomapan 100 or 200. Resolving power is ~90 lp/mm. The spectral sensitivity extends to approximately 700 nm, providing broad panchromatic coverage. Exposure latitude spans EI 200 to EI 1600 without development changes. Fomapan 400 is well known among analog enthusiasts for its affordable price point and a bold, high-contrast look that suits street, concert, and documentary photography. It pushes well to EI 800 and beyond, though grain becomes prominent. Compatible with standard black-and-white chemistry including D-76, Rodinal, HC-110, and Microphen. Available in 135 and 120 roll formats and large-format sheet film.
