Black-and-white, or monochrome, refers to images or designs that use only shades of black, white, and gray. This style emphasizes contrast and texture, allowing viewers to focus on shapes and forms without the distraction of color. Monochrome can be found in photography, art, and graphic design, often evoking a sense of nostalgia or timelessness. In photography, black-and-white images can highlight emotions and details that might be overlooked in color. Famous photographers like Ansel Adams and Henri Cartier-Bresson are known for their striking monochrome works. This approach remains popular for its ability to convey mood and atmosphere effectively.
