Photography in the United States
The practice and appreciation of photography in the United States began in the 19th century, when various advances in the development of photography took place and after daguerreotype photography was introduced in France in 1839. The earliest commercialization of photography was made in the country when Alexander Walcott and John Johnson opened the first commercial portrait gallery in 1840.
