Ilford SFX 200 135/36 black and white film

SFX 200 is a unique black-and-white film with extended spectral sensitivity in the red region up to 740 nm, which allows very creative and even dramatic shots. These properties can be enhanced further by using filters from yellow to deep red. Unlike other infrared materials, SFX 200 can be used in ordinary daylight. SFX 200 has a nominal speed of ISO 200/24°, which can be increased to ISO 800/30°. It can be processed in all the usual ways and in all ILFORD chemistry.
