Ilford XP2 Super 400 is a chromogenic black-and-white film designed for processing in standard C-41 color chemistry, which sets it apart from traditional silver-based black-and-white films. Instead of forming an image from metallic silver, it produces a dye-based image during development, resulting in fine grain and smooth tonal transitions. The film offers a wide exposure latitude, though its dye-based image is generally less archival than silver gelatin negatives.
