Upon returning to liberated Guinea-Bissau, Gomes filmed his country's independence ceremony (24 September 1974), fulfilling the desire of Amílcar Cabral that it should be Bissau-Guineans themselves capturing this historical moment on film. After freeing itself from colonial rule, Guinea-Bissau was visited by many reporters and progressive filmmakers and Gomes, given his knowledge of cinema, was in great demand to assist them, which allowed him to expand his skills. At the end of the 1970s, he worked as a photographer and cameraman for the Ministry of Information.
