Returning to Alabama in 1957, he briefly worked in a portrait studio before joining the Montgomery Advertiser newspaper staff.
In later years, he took travel photographs, corporate portraits and the occasional hard-news photograph. He also amassed about 100 magazine covers.
His work was gathered in two books, "Powerful Days: The Civil Rights Photography of Charles Moore" (1991) and "The Mother Lode," a 1983 pictorial guide to the California gold rush country he came to know as a longtime resident of Columbia, Calif.
Moore, who was divorced, also had lived in Massachusetts and North Carolina. He moved to Florida last year to be near family.
The genteel Moore could seem embarrassed by the attention he received for his most famous body of work.
"I know the importance isn't me, but the photographs," he told the Birmingham News in 2002.
"It's proof that the world learned a lot from them. Honestly, if those pictures made my native South, which I love, a better place . . . then I am darn proud of that."
In addition to his daughter Michelle of West Palm Beach, Fla., Moore is survived by three other children, Michael Moore and April Marshall of Dothan, Ala., and Gary Moore of Lewisville, Texas; his brother, Jim, of Conway, Mass.; seven grandchildren; and three great-grandchildren.
