|Camera Obscura at Cliff House in San Francisco|
Camera Obscura is Latin for 'dark room'. Let light from a pinhole or a lens into a dark room and it will project an image of the outside world on the opposite wall, so Camera Obscura is simply a fancy name for a very simple device. They have been around for millennia, Aristotle was familiar with the principle. Uniberp pointed out this one at Cliff House. Cliff House is a famous landmark in San Francisco. Those parking spaces out front are free, but there are only a few dozen, and being as this place is famous the odds of finding an open one there when you drive up are astronomical. Are you feeling lucky, punk?
|Caption from image: The Camera Obscura, which is seen at many seaside places, is a striking example of how rays of light can be reflected in a different direction by a mirror placed at a slant. In the roof is a mirror at an angle of 45°, and this catches a reflection of the scene outside. The rays are directed upon a magnifying lens, placed in the right position to focus them, and the magnified view is cast upon a white table below. The top containing the mirror can be rotated by means of a handle turning a series of gear wheels, so that an image of the view all round can be reflected upon the table. The Camera Obscura was invented by a Neapolitan physician named Porta who found that by passing light through a double-convex lens he obtained a brighter image|
ADDICTED TO LOVE (1997) - Official Movie Trailer
This reminded me of this movie (Addicted to Love) where Sam the jilted uses a Camera Obscura to spy on his ex-girlfriend. The images from the device make a few brief appearances in the trailer starting at the one minute mark. The movie is absurd. It was, however, entertaining. Comedy and stupidity are blood-brothers.
P.S. How to type a degree symbol on Linux: Ctrl + Shift + u (this will show an underlined u) and then the unicode value (in this case B0 ) and follow it by Enter.
