George Eastman Kodak introduced a camera called Brownie in February 1990 using the celluloid film. This camera was so popular that people were using this camera till 1960.

6. Single Lens Reflex Camera in 1933

In 1933 Exakta introduced the first single lens reflex camera using 127 mm roll film and in 1936 with 35 mm roll film.  The single lens reflex (SLR) cameras typically use mirrors and prism system allowing the photographer to view through the lens and see exactly what will be captured. This SLR technology became the main character in cameras and framed a whole new path of evolution.
