Claim: James Ambrose Cutting was an American photographer and inventor from New Hampshire that held three patents for improvements in the collodion process used to make Ambrotypes.
Evidence: James Ambrose Cutting (1814–1867) was an American photographer and inventor, sometimes called the inventor of the Ambrotype photographic process. He grew up in poverty on a farm in Haverhill, New Hampshire. In 1854, Cutting took out three patents relating to the process of creating images on glass using the wet plate collodion process. To create an ambrotype, the photographer sensitized a polished plate of glass by the wet plate collodion process and exposed the plate in a camera to produce a negative image.
