Black and white images are photographs or illustrations 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. Black and white photography has been popular since the early days of photography and is often used to convey a sense of nostalgia or timelessness. These images can evoke strong emotions and highlight details that might be overlooked in color. Many famous photographers, such as Ansel Adams and Henri Cartier-Bresson, are known for their black and white work, showcasing the power of light and shadow in their compositions.
