The History of Photo Paper

Photo paper has been used since the early days of photography and has undergone significant developments in terms of consistency and light sensitivity over time. It became popularized through the negative-positive photographic processes, as introduced by William Fox Talbot in 1841. In the 19th century, the ability to print images on paper revolutionized photography, as it allowed for the production of shareable and disposable photographs

One significant milestone in the history of photo paper was the invention of Velox by Leo Baekeland. Velox was the first commercially successful photographic paper that could be developed under artificial light. Baekeland’s invention was eventually sold to George Eastman for $1,000,000, further contributing to the development and widespread use of photo paper.
