Ilford FP4 Plus Black and White Negative Film

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. In addition to general photography, FP4 Plus is also suited to copying and internegative work, and has many applications in scientific, technical and industrial photography.

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 processing systems, including those which give the standard short fixing and washing times.

FP4 Plus 35mm film is coated on 0.125mm/5-mil acetate base and is available in 24 or 36 exposure cassettes, or in bulk lengths of 17 or 30.5 metres (56 and 100ft). FP4 Plus 35mm film is supplied in DX coded cassettes, suitable for all 35mm cameras.

Filter Factor: FP4 Plus film may be used with all types of filters (e.g. colour, polarising and neutral density filters) in the usual way. Follow the instructions given by the filter manufacturer.

The exposure increase in daylight may vary with the angle of the sun and the time of day. In the late afternoon or the winter months, when daylight contains more red light, green and blue filters may need slightly more exposure than usual.

Cameras with through-the-lens metering will usually adjust the exposure automatically when using filters. With some automatic exposure cameras, the correction given for deep red and orange filters can produce negatives under exposed by as much as 1½ stops.
