Ilford FP4 Plus is an exceptionally fine grain medium speed black and white film. It is ideal for high quality indoor and outdoor photography particularly when giant enlargements are to be made.

FP4 Plus is robust and will give usable results even if it is overexposed by as much as six stops or underexposed by two stops. It is compatible with all major black and white processing systems including those which give the standard short fixing and washing times. FP4 Plus 35mm film is coated on 0. 125mm5-mil acetate base and is available in 24 or 36 exposure cassettes or in bulk lengths of 17 and 30. 5 metres 56 and 100ft.
