Carpenter's work focused on the early development of 19th and 20th century
Mendocino County, California. Carpenter photographed panoramas of the coast, forests, and early industry, including logging and shipping. He documented the
Pomo people and early white settlers, including
Charmian London. In the 1960s, 700 glass plate negatives of Carpenter's photographers were found in the basement of the Sun House in Ukiah, the home where Carpenter's daughter Grace Hudson and her husband, John Hudson, lived. Local Ukiah photographer Robert Lee gathered the negatives and researched and created prints of the negatives, documenting the subjects seen in the images. It took forty years for Lee to complete the project. As a result, the first exhibition of Carpenter's work was held in 2006 at the
Grace Hudson Museum, also celebrating the museum's 20th anniversary. ==Further reading==
