Ilford SFX 200 is a medium speed black and white film for creative photography. It has extended red sensitivity (up to 740nm) and is especially suited for use with a filters to create special effects.
By using a very deep red filter, skies can be rendered almost black, and most green vegetation almost white. Its unusual tonal rendition ensures interesting results for a range of subjects, including portraits, landscapes, townscapes and architecture.
Best results are obtained in bright sunshine, or in the studio under tungsten lighting. SFX also has full panchromatic sensitivity to ensure good pictorial contrast with or without the use of a filter. It has a wide exposure latitude and is compatible with all normal developers. It is known for having a wide tonal range.
EXPOSURE RATING: SFX 200 has a speed rating of ISO 200/24° to daylight. The ISO speed rating was measured using ILFORD ID-11 developer at 20°C/68°F with intermittent agitation in a spiral tank.
USE OF FILTERS: SFX 200 film can be used with yellow, orange or red filters. The effect seen will depend on its transmission characteristics. The redder the filter, the more dramatic the effect. With very dark filters, exposure times can be very long, so the use of a tripod is recommended.
