Pan F Plus- Rated at ISO 50;- Exceptionally fine grain;- Outstanding resolution & sharpness.PAN F PLUS at ISO 50 is the slowest of the ILFORD films, but when image quality, fine detail and lack of grain are more important than film speed, PAN F PLUS excels. Suitable for subjects ranging from architecture to still-life and portraiture to medical. Mural size enlargements from PAN F PLUS negatives show an outstanding range of tone and detail when the film is carefully exposed and processed. For scientific, technical and copying applications, PAN F PLUS can be developed to a higher contrast.
