I have to digress for a moment to tell you that during the heyday of the great screen sirens, the general practice when stars showed signs of aging was to use gauze in front of the lens. Then they found out that the system was flattering to the face but no good at all for the look. So the cameraman would take a cigarette and burn out two holes in the gauze for the eyes. In this way, the face was nice, if somewhat hazy, and the eyes sparkled, but of course it meant that the actress couldn’t move her head at all. Next, they moved away from gauze to diffusion disks, but there they ran into another problem. A star would tell the cameraman: “My friends say that I must be getting old because you’re using diffusion and it shows when my close-ups are cut into the picture.” The cameraman would answer: “I can fix that.” And it was very simple. All he had to do was to diffuse the rest of the picture, so that when the close-ups were cut in it didn’t show.
