"The best action always occurs during reloading and rewinding"

 "The  Bell and Howell Eyemo 35mm camera, which came in several different models, some spring driven and others battery powered, some with only a single lens and others with a spider turret holding three lenses. The Army Signal Corps estimated that Eyemos accounted for about 90 percent of its combat motion-picture footage, and the percentage was approximately the same for the other services. A 100-foot roll of 35 mm film weight about four pounds and cameramen carried up to 10 rolls. Most cameramen had to hand-hold their cameras. The Eyemo lacked special grips for steady hand-holding. Much of World War II footage bounces, jiggles and wavers. Although an Eyemo could be modified to hold a 400-foot magazine, that made the camera impossibly bulky for front-line duty.

    A 100-foot roll zipped through the camera in just a little more than a minute and then the cameraman had to reload, a tricky process even under ideal conditions, requiring him to thread the film carefully through the camera's inner rollers, gears and gates. With a motor-driven model a photographer could shoot 100 feet without any interruptions, although then he had to tote along a battery that further burdened his already overburdened body.
