Black-and-white images are photographs or illustrations that use only shades of black, white, and gray. These images lack color, which can create a timeless and classic feel. They often emphasize contrast, texture, and composition, allowing viewers to focus on shapes and patterns without the distraction of color. Historically, black-and-white photography was the standard before the advent of color film. Many famous photographers, such as Ansel Adams and Dorothea Lange, used this medium to capture powerful images that convey emotion and storytelling. Today, black-and-white images are still popular in art and photography for their aesthetic appeal and ability to evoke nostalgia.
