Setup, Compatibility & Care
Loading and Handling: Load the film in subdued light or complete darkness, similar to any other black and white film. However, be mindful that excessive exposure to strong infrared light *before* shooting could potentially fog the film, although this is generally less of a concern during daylight shooting for a fully exposed roll.
Camera Compatibility: This is a standard 135 film cartridge and is compatible with any 35mm camera. Ensure your camera's light seals are in good condition to prevent light leaks.
Filter Usage: For the most dramatic effects, a dark red filter (e.g., #25, #29, or #70) is highly recommended. Attach the filter to your lens *before* composing and metering.
Exposure Adjustments: Due to the filter's effect and the film's infrared sensitivity, you will typically need to increase exposure. A common starting point is to add 2-3 stops of exposure (or adjust your meter accordingly). Consult your camera or filter manufacturer's recommendations for specific guidance.
Development: Ilford SFX 200 can be developed in standard black and white developers. Follow the recommended development times for ISO 200 or adjust slightly based on your desired contrast and developer choice. Some photographers prefer specialized development techniques for infrared films, but standard methods usually yield good results.
Storage: Store unexposed film in a cool, dry place, preferably in its original packaging. Exposed film should be processed as soon as possible.
