About this film

Foma Ortho 400 135/36 is black-and-white film rated at ISO 400 in 135 format with 36 exposures.

Image character

Orthochromatic sensitivity emphasises blue and green while rendering reds darker; grain remains controlled for ISO 400.

Best uses

Graphic street work, landscape, architecture, creative portraiture and handling under a red safelight.

Practical advice

Skin and red objects appear darker than with panchromatic film. Judge the effect by subject and process in standard B&W chemistry.

Processing: standard B&W processing. I recommend labelling the actual EI and any push/pull or scanning requests before handing the film to a lab.
