Remarried, and with a new daughter, Bullock traveled throughout California from 1945 to 1946, producing and selling postcard pictures while co-owning a commercial photographic business in Santa Maria. He also worked on developing a way to control the line effect of solarization for which he later was awarded two patents. In 1946, he settled with his family in Monterey, where he had obtained the photographic concession at the Fort Ord military base. He left the concession in 1959, but continued commercial free-lance work until 1968.
