The unorthodox images which leapt from the walls of our house seemed as eerie as the darkroom experience itself: there was a photograph of a llama's head as viewed through a distorting fish-eye lens, there was a photograph of a shredded poster of a man's face, and there were many abstract photos which seemed to defy description.
Hence the lens gets its name 'the fish-eye lens. A globe refracts the light that reaches it from all directions, and if it is placed as the lens is in the detectascope so that one half of it catches the light, all this light will be refracted through it.
"Look through it," he replied simply, still at work on some other apparatus he had brought. I looked. In spite of the smallness of the opening at the other end, I was amazed to find that I could see nearly the whole room on the other side of the wall. "It's a detectascope," he explained, "a tube with a fish-eye lens which I had an expert optician make for me." "A fish-eye lens?" I repeated. "Yes.
Are stockings mended in the same old way, so that the toes look through the open mesh? Have college sweeps learned yet to tuck in the sheets at the foot? Do old-clothes men Fish-eye? Do you remember him? do old-clothes men still whine at the corner, and look you up and down in cheap appraisal? Pop Smith is dead, who sold his photograph to Freshmen, but has he no successor?
I put my eye to the eye-piece and gazed through the bulging lens of the other end. I could see almost the whole hall. "That," he explained, "is what is known as a fish-eye lens a lens that looks through an angle of some 180 degrees, almost twice that of the widest angle lens I know of." I said nothing, but tossed my own crude invention into the corner, while Craig went back to work.
"Water Babies" perhaps gives us the best idea of existence below the water, but if we spend one day each month for a year in trying to imagine ourselves in the place of the fish, we will see that a fish-eye view of life holds much of interest.
"You certainly are the actin'est kid on this set, I'll tell the lot that. Of course these close-ups won't mean much, just about one second, or half that maybe. Or some hick in the cuttin' room may kill 'em dead. Come on, give me the fish-eye again. That's it. Say, I'm glad I didn't have to smoke cigarettes in this scene. They wouldn't do for my type, standin' where the brook and river meet up.
It was a detectascope, invented by Gaillard Smith, adapter of the detectaphone, an instrument built up on the principle of the cytoscope which physicians use to explore internally down the throat. Only, in the end of the tube, instead of an ordinary lens, was placed what is known as a "fish-eye" lens, which had a range something like nature has given the eyes of fishes, hence the name.
He has devised a fish-eye camera that 'sees' over a radius of one hundred and eighty degrees not only straight in front, but over half a circle, every point in that room. "You know the refracting power of a drop of water. Since it is a globe, it refracts the light which reaches it from all directions. If it is placed like the lens of a camera, as Dr.
I did so and was amazed to find that through a hole less than a quarter of an inch in diameter the brass tube enabled me to see the entire room next to us. I looked up at Kennedy in surprise. "What do you think of this, Miss Kendall?" I asked, moving the settee out of her way. "What do you call it?" "That is a detectascope," he replied, "a little contrivance which makes use of the fish-eye lens.
