In exactly the same way our eyes are shocked by the movies when a dazzling white light is flashed on the screen where a somewhat darkened scene has just vanished. The pupil is caught unawares, is not instantly able to protect the eye, and, besides, must use up a certain amount of energy in adapting itself to the new condition. Such a shock once or twice during the evening might easily be forgiven and forgotten, might, in fact, be hardly felt at the time; but fifty such shocks in a five-reel photoplay would certainly weary the eye, and a play of that sort could hardly be called beautiful.

The fault which we have just named lies in the joining of scenes. But it is not, as a rule, necessary to connect scenes or sections of a film so that there is a jump from the darkest dark to the whitest white, or vice versa. This can be avoided, of course, by the device of “fading out” one scene and “fading in” the next, which gives the eye time to adapt itself, or by “fading down” or “up” just far enough to match the exact tone of the next picture. The shock can also be avoided by joining various sections of the film in a series of steps of increasing brightness or darkness.

The eye is hurt, we have said, by a sharp succession of black and white. It is also hurt by a sharp contrast of whites and blacks lying side by side on the screen. Such extremes are avoided in paintings. The next time you are in an art museum please compare the brightest white in any portrait with the white of your cuff, or your handkerchief, or a piece of paper. You may be surprised to discover that the high light in that painting is not severely white. It is rather grayish or yellowish, soft and easy to the eye. Observe also that the darkest hue in that painting is far from the deepest possible black. The extremes of tone are, in fact, never very far apart, and are therefore easily grasped by the eye without undue strain.

And while you are thinking of this practice of painters, you might compare it with the similar practice of composers of music. Your piano has many keys, the highest one in the treble being extremely far from the lowest one in the bass. Yet if you examine the score of any single piece of music you will discover that the highest note in that piece is not so very far from the lowest note in the same piece. It might have been possible to use the entire keyboard, but the composer has been wise enough not to try it. His extreme notes are so near together that the ear is able to catch them and all the subtle values of the music in between, without being strained by the effort.

It seems, therefore, that in artistic matters moderation is a good thing, is, in fact, necessary to produce real beauty. But moderation in the movies is not yet a widely accepted gospel. Too often we find that the dazzling flood of rays from a strong searchlight blazes over several square yards of the silver screen, while at the same moment, on adjoining parts of the same screen hang the deep shades of night. The contrasts are sharp as lightning, not only in the scenes, but also in the sub-titles which are cut in between. Our eyes gaze and twitch and hurt, until it is a real relief to step out and rest them upon something comparatively moderate, like the electric signs on Broadway.

If there were some mechanical difficulty which made this clashing effect of the motion pictures necessary, we could never hope for beauty on the screen; for no art can achieve beauty by producing pain. But we know from the work of such directors as James Cruze, D. W. Griffith, Allan Dwan, Rex Ingram, and John Robertson, that the moving picture camera is capable of recording light gray and dark gray, as well as steel white and ebony. They have shown us that it is possible to produce sub-titles with light gray lettering against a dark gray ground, and that such a combination of tones is pleasing to the eye. They have shown us that it is possible to screen a lady of the fairest face and dressed in the snowiest gown so as to bring out the softest tones of light and shade, yet show nothing as dazzling as snow and nothing as black as ebony.
