Since Hall was part of the Guild, he was able to work as an assistant cameraman at the side of many influential cinematographers such as Hall Mohr, Ernie Haller, Burnie Guffey and Ted McCord, who were all part of the ASC. Following a year of working as an assistant cameraman, he was awarded the chance to be the camera operator on the television series Stoney Burke. In 1963, he began filming another television series called The Outer Limits. Then, in 1964, he shot his first feature-length black and white film, Wild Seed, which was made in roughly 24 days with Producer Albert S. Ruddy.
