This infrared film is one I'm quite pleased to use. It loads and unloads as any other B&W film in subdued light unlike Kodak HIE of years ago. My choice of format is 120 which I shoot in my Mamiya 645. This film format is easier for me to handle in my darkroom and I need not expose 36 frames as with 35mm to complete the roll. 645 yields 15 exposures allowing me at least 2 frames per subject just to be safe.
I have found that using a consistent exposure of f8 @ 1 second, SFX produces a great negative from which to then develop a great print. You may chose to bracket around f8 or the 1 second shutter speed if you like. Of course, I'm exposing in "sunny 16" lighting which means very bright sun and deep dark shadows. The sun light is behind me and shinning directly on my subject. This enhances the IR effect on blue skies and green foliage. The sky turns dark and the greens turn "Twilight Zone" white.
My Beseler 23C allows me the option of printing with variable contrast filters. My favorite is the 3 1/2 contrast when using Ilford MultiGrade RC paper. My developer for film is ILFOSOL 3 (one shot) and for paper it's Ilford Multigrade. Stop baths are any variety. Ilford Rapid Fixer works for both film and paper as does Ilford Wash Aid (like Kodak Hypo) but Ilford Ilfotol (like Kodak Photo Flow) is only used with film.
I trust this brief discussion will prove helpful to anyone exploring Ilford SFX 200!
If I can help in any way, post me a comment. I don't have all the answers but I'll do my best.
