help Ilford SFX 200 FAQ
Is Ilford SFX 200 a true infrared film?
No. SFX 200 is a black-and-white film with extended red sensitivity reaching approximately 740 nanometers, so it produces infrared-like effects without being a fully infrared stock. [Ilford SFX 200 guide](https://www.ilfordphoto.com/using-ilford-sfx-part-1/)
What happens when SFX 200 is used with a deep red filter?
A deep red filter can render blue skies very dark and green vegetation very light, creating the classic infrared-style contrast. Ilford recommends filters because they make the extended red response much more visible. [Ilford SFX 200 product information](https://www.ilfordphoto.ca/product/sfx200-120-roll-film/)
Can Ilford SFX 200 be developed in normal black-and-white chemicals?
Yes. Ilford says SFX 200 is compatible with normal black-and-white developers and can be processed like a conventional black-and-white negative.
