A remarkable instance of this is recorded by Mr. Myers in an article in the Arena, where the analogy to a camera obscura is very close. The camera reflects everything that happens. Nothing is either great or small to its impartial lens. But if you do not happen to be in the right place, or if the room is not properly darkened, or if the white paper is taken off the table, you see nothing.
The men and women in the streets were mere puppets, without motives in themselves, or interest to him. He saw them all as on the ever-changing field of a camera obscura. She she alone and altogether was his universe, his well of life, his incarnate good. For six evenings she came not.
His mind seemed a camera obscura in which everything that passed before it was recorded permanently, but he added in the rendering of its record nothing which sprang from human emotion, or which involved that remoulding of the perception that makes it conception, and individual.
He compared the mechanism of the eye with that of Porta's "Camera Obscura," but made no attempt to explain how the image formed on the retina is understood by the brain. He went carefully into the question of refraction, the importance of which Tycho had been the first astronomer to recognise, though he only applied it at low altitudes, and had not arrived at a true theory or accurate values.
The "camera obscura," as used at a modern fort, is in itself a most interesting contrivance. While no elaborate description of it can be attempted here, it will be enough to explain to the reader that, in the camera room, which is darkened, is a large white table covered with white oil-cloth, or other white substance. On this white surface is drawn a plan of the harbor to be defended.
He was a good colourist, 'with a rare truth to nature and a marvellous distinctness of eye and precision of hand. Minute as his execution was, his touch was 'free and soft. His best pictures are 'like nature's self seen through the camera obscura. An instance often given of his exquisite finish is that of a broom in the corner of one of his pictures.
It is said that Kepler saw this dark spot while looking at the sun in a camera obscura. As a camera obscura is actually a telescope, magnifying objects in proportion to the focal length of the lens employed, he may be said to have first seen these spots with the aid of an optical instrument.
If we think of the moving pictures as a source of entertainment and esthetic enjoyment, we may see the germ in that camera obscura which allowed one glass slide to pass before another and thus showed the railway train on one slide moving over the bridge on the other glass plate. They were popular half a century ago.
I began to pray if you will excuse me for mentioning it. My whole past life appeared like the figures that glide over the field of a camera obscura not an abiding fact in it all. A cloud gathered about me, and hangs about me still. I call, but no voice answers me out of the darkness, and at times I am in despair.
Memory is in this respect like the lens of a camera obscura: it contracts everything within its range, and so produces a much finer picture than the actual landscape affords. And, in the case of a man, absence always goes some way towards securing this advantageous light; for though the idealizing tendency of the memory requires times to complete its work, it begins it at once.
