In 1892, legendary inventors Thomas Edison and William Kennedy Dickson were the first to use 35mm film to shoot film on their historic analog film cameras. Over the years, all kinds of formats have appeared and disappeared, but it was 35mm that stood the test of time and became the standard film format for movie making.
Only later did they begin to experiment with the use of 35 mm film in still cameras. It was German optical engineer, Oskar Barnack, who would eventually be credited with popularizing the still photography format when he invented the first of the legendary Leica 35mm cameras. Now 35mm film is considered the standard film format for photographs worldwide.
