TECHNICAL INFORMATION

HP5 PLUS

ISO 400/27º, BLACK AND WHITE PROFESSIONAL FILM

FOR HIGH PRINT QUALITY AND FLEXIBILITY IN USE

ILFORD HP5 Plus is a fast black and white film. It is ideal for action, available light and general-purpose

photography. HP5 Plus is compatible with all major processing systems, including those which give the standard

short fixing and washing times.

Although rated at ISO 400/27º, HP5 Plus can produce high quality prints when exposed at meter settings up to

EI 3200/36 and given extended development in ILFORD ILFOTEC DD-X, ILFOTEC HC, MICROPHEN or

ILFOTEC RT RAPID developers.

HP5 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 30.5 metres (100ft). HP5 Plus 35mm film is

supplied in DX coded cassettes, suitable for all 35mm cameras.

HP5 Plus roll film is coated on 0.110mm/4-mil clear acetate base with an anti-halation

backing which clears during development. It is available in 120 lengths and is edge

numbered 1 to 19.

HP5 Plus sheet film is coated on 0.180mm/7-mil polyester base with an anti-halation

backing which clears during development. It is available in a wide range of standard sizes. The emulsion faces

the user when sheet film is held in the position shown.

EXPOSURE RATING

Best results are obtained at EI 400/27, but good image quality will also be obtained at meter settings from EI

400/27 to EI 3200/36. It should be noted that the exposure index (EI) range recommended for HP5 Plus is

based on a practical evaluation of film speed and is not based on foot speed, as is the ISO standard.

SPECTRAL SENSITIVITY

Wedge spectrogram to tungsten light (2850K)

HP5 PLUS Technical Information FILTER FACTORS HP5 Plus film may be used with all types of filters (eg 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.

HP5 PLUS Technical Information DEVELOPMENT TIMES The table below gives development times for both manual and machine processing HP5 Plus. These times will produce negatives of average contrast suitable for printing in all enlargers. The development times are intended as a guide and may be altered if a different result is needed. For manual processing in spiral tanks and deep tanks, the development times are based on intermittent agitation.

HP5 PLUS Technical Information CHARACTERISTIC CURVE HP5 Plus film developed in ILFORD ILFOTEC HC (1+31) stock for 6½ minutes at 20ºC/68ºF with intermittent agitation. This curve is also representative of roll film and sheet film formats. PROCESSING HP5 Plus can be processed in all types of processing equipment including spiral tanks, rotary processors, dishes/trays, deep tanks and automatic processors. Standard capacity figures and replenishment rates can be maintained.

HP5 PLUS Technical Information Fix The recommended fixers are ILFORD RAPID FIXER or ILFORD HYPAM FIXER. ILFORD RAPID OR HYPAM FIXERS Dilution 1+4 Wash Wash the films in running water for 5–10 minutes at a temperature within 5ºC (9ºF) of the process temperature. Or see note below for greater economy when using spiral tanks.
