Antique and vintage cameras are valued by collectors for many reasons, from the historical significance of 19th century wood cameras to the fine optics of classic vintage Leicas. Kodak and Polaroid are two other big names in camera collecting, as is Bolex in movie cameras.
The principles of the camera obscura - a simple light projection box - have been understood for thousands of years, but it wasn't until the late 18th century that Thomas Wedgwood discovered he could make simple prints using silver nitrate exposed to the sun. Over the next 100 years, a series of technical advances brought cameras into everyday life.
Nicephore Niepce and Louis Daguerre formed a partnership in 1829, and figured out a new chemical bath for prints, which shortened the exposure process to eight hours. Daguerre continued this research until he perfected the Daguerreotype, a print made on silver that was used up until the mid 1850s. Daguerreotypes and other formats (e.g. cyanotypes, ambrotypes, tintypes) were made with wood cameras, which were essentially camera obscuras with lenses, allowing for clearer image refraction.
It wasn't until George Eastman's 1885 invention of film that cameras got smaller - with his Kodak film loaded in, you would send the whole camera back to the factory to have it developed. Oskar Barnack began experimenting with 35 mm film in 1914 and built some prototypes of what eventually become the Leica I, the first practical 35 mm camera, released in 1925.
More improvements came when Kodak introduced the Retina I, the first camera to use a modern 135 film cartridge. Photography soon became affordable to all, even before the 1947 introduction of Polaroid's instant camera.
Development of movie cameras kept pace, building atop the basic slide projection technology (magic lantern) which had been in use since the 1500s. The first movie cameras were developed around 1888, and Thomas Edison produced the first copyrighted film in 1894. In 1895, the Lumiere brothers of France first showed off their 'Cinematographe,' a handheld combination projector and camera, in the first commercial public film screening.
