Black-and-white, often abbreviated B/W or B&W, is a term referring to a number of monochrome forms in visual arts. Most forms of visual technology start out in black and white, then slowly evolve into color as technology progresses. Even after color film was readily available, black-and-white photography continued to dominate for decades, due to its lower cost and its “classic” photographic look.
