After the FSA disbanded, Parks remained in Washington, D.C. as a correspondent with the Office of War Information, where he photographed the all-black 332d Fighter Group. He was unable to follow the group in the overseas war theatre, so he resigned from the O.W.I. He would later follow Stryker to the Standard Oil Photography Project in New Jersey, which assigned photographers to take pictures of small towns and industrial centers. The most striking work by Parks during that period included, "Dinner Time at Mr. Hercules Brown's Home, Somerville, Maine" (1944); "Grease Plant Worker, Pittsburgh, Pennsylvania" (1946); "Car Loaded with Furniture on Highway" (1945); "Self Portrait" (1945); and "Ferry Commuters, Staten Island, N.Y." (1946).
