The history of film spans from 1727 when Johann Schulz discovered that silver nitrate changed color with light exposure, enabling the first camera. In 1814, the Camera Obscura was used to take the first photograph but images were not permanent. In 1837, Louis Daguerre invented the Daguerreotype which produced the first clear, permanent photographs. Throughout the 19th century, improvements continued such as making multiple copies possible and faster exposure times. In 1888, George Eastman created the first roll film camera, growing the commercial film industry. Major developments in the 20th century included color film in 1963, the first digital camera in 1974, and camcorders enabling consumers to record video in 1980. Camera technology
