If you're a photographer, you probably use an inkjet printer. Most likely it's an expanded gamut inkjet printer—one that uses six to eight inks, rather than the standard four (they're really dyes, but most folks call them inks). The most common combination of expanded gamut ink includes the four standard process colors—cyan, magenta, yellow and black (CMYK)—plus light cyan and light magenta. You may also have a choice of black inks, like glossy or photo black, matte black, light black, and even light light black (seriously!).
