Color film is a type of photographic film that captures images in color rather than just black and white. It works by using layers of light-sensitive chemicals that react to different wavelengths of light, allowing for a full spectrum of colors to be recorded. This technology revolutionized photography and cinema, making images more vibrant and lifelike. The first successful color film process was developed in the early 20th century, with notable advancements made by companies like Kodak and Agfacolor. Today, color film is widely used in both still photography and motion pictures, contributing to the rich visual storytelling seen in modern cinema and art.
