images of the future
In the 1930s, Harold Edgerton tried a new way of freezing motion for photographs. He designed the strobe light, a lamp that sends out an intense flash of light for the merest fraction of a second. When a high speed strobe light is used with a camera, the light temporarily takes the place of the camera's shutter.
Another specialized use of cameras that helps us see the world in new ways is photomacrography, which enlarges small objects. The scanning electron microscope, an even more refined microscope/camera combination, produces crystal clear images that magnify the original as much as a million times.
The Hubble Space Telescope, which is fitted with numerous digital cameras, is a giant orbiting camera that has produced spectacular pictures of stars, planets, and nebulae. In recent years special cameras fitted in steel housings have been lowered to the deepest depths in the world's oceans.
Most cameras made for amateur photographers these days are ''point and shoot'' models, which contain a computer chip that automatically judges focus, exposure time, flash, etc. just over a decade ago, the first modern single use, or disposable camera made its appearance. Constructed with automatic machinery, high quality plastic lenses, and improved color negative films. even more important is the arrival of digital cameras, which are opperated by a chip that automatically and constantly monitors everything . They also enable digital models to be the first cameras that operate without film or photographic plates.
In many digital models, you can see the pictures you've taken on a small screen, and if you don't like it you can erase it. Since the images are stored in the computer, they can easily be printed in homemade greeting cards, newsletters, E-mails, or other documents.
Digital cameras put you in the control of every step of the photographic process. You can even edit your photos. Where photographs once recorded the world with greater realism than any painting could match, now they can even take on whatever reality you choose.
