wndion of the players. Let the play get beyond the center of the camera field somewhat and then bring it into the lens area with a smooth swing. Avoid the dizzy jerks to right and left as the ball is feinted or short passes are made There are few sports other than basketball that offer such continuous, un- interrupted action, with little time for the cameraman to rewind his spring motor without missing some of the play. Since most cameras carry 100* of film, a re- loading is necessary after about 4 minutes of filming. The answer is:-use two camera- men with two cameres. When #1 cameraman finishes his first film, #2 starts his roll. 31 #2 completes the second hundred feet of film, #1 carries on with the third hundred,--and so on through the gamee The intervals between shooting will allow for reloading. The popular 50° magazine loading motion picture cameras make this doubling unnecessary, but the spring drives require frequent rewimling. The Cinema Laboratory camera is one of the advanced 16 mm. models with interchangeable film charbers, so that with an assistant to reload the chambers, one tripod set up is ail that is necessary. Even ti «gh the spring drive will run 32' of film at a wind- ing, Often in the "no tip-off" game, the spring has run down before a score has ‘cen madee The ideal camera equipment is the motor drive type with external 400! film chambers,--qmough film to cover an entire half of a gane continuous Ly. & very satisfactory gane amlysis that will be quite complete my be made with 8 rolls (800) of film. Some coaches prefer to use less footage by "spotting" his film, part at the start of the game and some during the various periods of play. It is our hope that this “illuninating advice" and camera counsel my en- ‘ourege other besketball mentors throughcut the country to make motion picture analyses of their tean's play. By these studies they may perfect their boys in one of the most fascinating am popular of the American spor ts--Basketball. Dr. Janes E.
