This document provides a history of photography from its origins to modern applications. It discusses early innovators like Niepce, Daguerre, and Talbot who developed the first photographic processes in the 1820s-1840s. The daguerreotype and calotype processes allowed photographs to be taken and reproduced. Advances like the wet plate collodion process in the 1850s led to photographs being widely used to document events like the Civil War. Photography was also used in science, medicine, industry, and to document social issues. Further innovations driven by the development of more portable cameras expanded photography's uses through the late 19th century until it became widely accessible to the public by the late 1880s.
