The history of photography began with ancient civilizations using camera obscuras to project images on walls. In the 16th century, lenses were added to camera obscuras to improve image quality. By the 17th century, camera obscuras became portable. In 1800, Thomas Wedgwood created the first photographs on paper treated with silver nitrate. Nicéphore Niépce combined the camera obscura with photosensitive paper in 1816.

George Eastman founded the Eastman Dry Plate Company in 1880, producing dry plates and roll film, launching modern photography. In 2004, Kodak ceased production of film
