TECHNICAL INFORMATION

SFX 200

BLACK AND WHITE CAMERA FILM WITH EXTENDED RED

SENSITIVITY FOR CREATIVE PHOTOGRAPHY

ILFORD SFX 200 is a medium speed black and white camera film for creative photography. It has extended

red sensitivity (up to 740nm) and is especially suited for use with a red filter to create special effects. For

example, 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 has a wide tonal range.

AVAILABILITY

SFX 200 film is coated on 0.125mm/5-mil grey acetate base which gives good halation protections.

SFX 200 is available in 36 exposure DX coded cassettes, suitable for all 35mm cameras.

SFX 200 is also available as120 roll film, edge numbered 1 to 19.

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.

It should be noted that the exposure index (EI) range recommended for SFX 200is based on a practical

evaluation of film speed and is not based on foot speed, as is the ISO standard.

SFX 200Technical Information USE OF FILTERS SFX 200 film can be used with yellow, orange or red filters, but 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. Below is a guide to filter factors for various filter colours.

SFX 200Technical Information PROCESSING SFX 200 can be processed in all types of processing equipment, including spiral tanks, rotary processors, deep tanks and automatic processors. Standard capacity figures and replenishment rates can be maintained. SFX 200 is very robust in processing and will tolerate less than ideal processing conditions. Also, it will not contaminate the processing chemicals. DEVELOPMENT TIMES The table on page 4 gives development times for both manual and machine processing.

SFX 200Technical Information PROCESSING Processing at Different Temperatures SFX 200 film can be processed over a range of temperatures. Approximate development times at temperatures other than 20°C/68°F may be calculated from the charts below. For example, if 4 minutes at 20°C/68°F is recommended, the time at 23°C/73°F will be 3 minutes and the time at 16°C/61°F will be 6 minutes.

SFX 200Technical Information Fix The recommended fixers are ILFORD RAPID FIXER or ILFORD HYPAM FIXER. Wash Wash the films in running water for 5–10 minutes at a temperature within 5ºC (9ºF) of the process temperature. Or see note below for greater economy when using spiral tanks.
