 By the end of 1928 he was credited with developing several new camera angles. Cronjager was lauded by industry magazines such as Variety for his inventive camera work in 1928's Warming Up, which added realism to the efforts of Dix as a baseball pitcher. In September 1928 Cronjager became involved in a minor controversy. The film industry was becoming unionized, and Cronjager was resistant to joining. When Dix insisted Cronjager photograph his next film, Moran of the Marines, the union threatened to strike if the cinematographer was hired without becoming a union member. Cronjager joined the union at the request of the studio, averting the threatened union action. Throughout his career, Dix attempted to have Cronjager as the cinematographer on his films.
