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. It is commonly used in photography, art, and graphic design to create a timeless or classic feel. Monochrome can evoke strong emotions and highlight details that might be overlooked in color images. Famous photographers like Ansel Adams utilized black-and-white techniques to capture stunning landscapes, showcasing the beauty of light and shadow. This approach remains popular in various creative fields for its simplicity and elegance.
