Parks renewed his search for photography jobs in the fashion world. Following his resignation from the Office of War Information, Parks moved to Harlem and became a freelance fashion photographer for "Vogue" under the editorship of Alexander Liberman. Despite racist attitudes of the day, "Vogue" editor, Liberman, hired him to shoot a collection of evening gowns. Parks photographed fashion for "Vogue" for the next few years and he developed the distinctive style of photographing his models in motion rather than in static poses. During this time, he published his first two books, "Flash Photography" (1947) and "Camera Portraits: Techniques and Principles of Documentary Portraiture" (1948).
