replaced the stationary base with a rotating one, which allowed the camera to have film installed on either side, which was necessary for the 3 negative rolls to occur. Arnold's contributions were not limited to camera equipment as back in the 1920s he had created the "Arnold light", an incandescent light to replace the older arc lights. In 1952 Arnold perfected a new lighting technique which utilized a new reflected type set, first utilized in the production, Scaramouche. For the 1952 film The Wild North, Arnold developed a camera heater which allowed cameras to film in very low temperatures. The heater could be adapted for any type of movie camera. Also in 1952, Arnold developed the jeep-mounted crane. He came up with the design to fill the need of his studio for rugged mobile transport to move cranes quickly from one location to the next. In October 1952 he was given an "Award of Fellow" from the Society of Motion Picture and Television Engineers. For the 1952 film, Julius Caesar, Arnold invented "skylight", an overhead lighting platform which used reflected light to produce shadowless lighting for indoor scenes. In 1953 Arnold invented a horizontal film travel camera, which was ahead of its time. It wasn't used by the studio until 1955, with the advent of 65mm. For the 1955 film Lust for Life'', Arnold developed a process which allowed Van Gogh's paintings to be shot with better clarity than simply filming with a camera. Arnold served on the board of governors for the ASC from its inception in 1919 until 1955. In 1956, he was elected an alternate board member. Arnold retired in 1956, after a career of 32 years with MGM, the last 26 of which were spent as head of MGM's camera department. Over the course of his career he invented hundreds of pieces of camera equipment. He was the only ASC member to serve 7 years as the organization's president. While head of the MGM camera department, Arnold was known for being a company man, requiring the cinematographers he supervised to use the glamorous cinematographic style MGM was known for, and coming down quite hard on those photographers who didn't want to conform to the MGM style.
