Ilford SFX 200 is a medium-speed black-and-white negative film in 120 roll format. With a nominal sensitivity of ISO 200/24°, broad exposure latitude, and a wide tonal range, it is suited to fine-art and pictorial photography.
Its extended red sensitivity enables infrared-style effects with color filters. A deep red filter produces the strongest effect, making blue skies appear nearly black and green vegetation nearly white. Yellow, orange, and light red filters provide additional creative effects.
- Peak red sensitivity reaches 720nm and can extend to 740nm when a deep red filter is used.
- Without a filter, the film provides full panchromatic sensitivity.
SFX 200 can be loaded in subdued light and processed with standard black-and-white developers to produce negatives with moderate contrast.
