Fomapan 400 Action is a pan chromatically sensitized, black-and-white negative film designed for taking photographs under unfavorable light conditions or using short exposure times. The film meets high requirements for low granularity, good resolving power and good contour sharpness. Fomapan 400 Action has a nominal speed rating of 400 ISO, but due to its wide exposure latitude the film gives good results even when overexposed by 1 exposure value or underexposed by 2exposure values without any change in processing times.
