Foma Ortho 400 120 black and white film

Foma Fomapan Ortho 400 is a fast orthochromatic black-and-white medium-format roll film with a nominal speed of ISO 400/27°. Its insensitivity to red light gives a distinctive tonal rendering — darkening reds and oranges while lightening blues and greens — making it a creative choice for portrait, landscape and fine-art photography. It can be used from ISO 160 to 1600 in standard black-and-white chemistry.
