Ilford PAN F Plus Ultra-Fine Grain Black and White Film, ISO 50, 120 Size ILFORD PAN F Plus is an extremely fine grain black and white film. When given standard development it has a speed rating of ISO 50/18° to daylight. In addition to its ultra-fine grain, PAN F Plus has outstanding resolution, sharpness and edge contrast. These characteristics enable the very highest image quality to be achieved and make PAN F Plus the natural film choice where fine detail and lack of grain are more important than film speed. Mural size enlargements from PAN F Plus negatives show an outstanding range of tone and detail when the film is carefully exposed and processed. PAN F Plus has good exposure latitude and gives prints with exceptional brightness and tonal range. PAN F Plus is compatible with all major processing systems including those which give the standard short fixing and washing times. There is no need to change standard processing techniques when switching to PAN F Plus from PAN F, or any other ISO 50/18° film. Development times, however, are different. PAN F Plus is very robust during processing, giving excellent results under most conditions, and will also tolerate processing conditions that are less than ideal. PAN F Plus 35mm film is supplied in DX Coded cassettes, suitable for all 35mm cameras. DX Coded cassettes mean that the film speed of ISO 50/18° is set automatically on most cameras. These cassettes are very strong and have the end caps firmly fixed to the body. This ensures the caps remain in position during rough handling. PAN F Plus 35mm film has a neutral base tint which enables easy print contrast assessment on the light box. For easy negative identification, it also has bold frame numbering for whole frames and letters to indicate half frame numbering.
