PROCESSING
If HP5 Plus film has been inadvertently exposed at settings below EI 250 / 25, the following guide will ensure
usable negatives are obtained. Obviously, the quality of negatives processed in this way will not be so high as
conventionally processed ones.
Note. Development times may need adjusting to suit individual processing systems and working practices. If an
established system is producing good results, adjust the recommended development times until the desired
contrast level is obtained. Development times for some other manufacturers’ developers are included for your
convenience and are only a general guide. Other manufacturers can and do change their product
specifications from time to time, and the development times may change as a result.
Processing at Different Temperatures
HP5 Plus film can be processed over a range of temperatures. Approximate development times at temperatures
other than 20°C/68°F may be calculated from the charts below. For example, if 6 minutes at 20°C/68°F is
recommended, the time at 23°C/73°F will be 4
½ min and the time at 16°C/61°F will be 9 min.
