George Eastman
Eastman was an inventor. He invented the “dry plate’ and the camera. He also made up the name Eastman “Kodak”. George had a very exciting life. He invented a really cool thing.
He invented lots of things one of which was the camera. George Eastman was a very important inventor from Rochester, NY. George came up with the name “Kodak” for no known reason.
George Eastman invented the camera in New York also known asRochester, NY. George Eastman invented the camera in a small room in his basement.
George Eastman invented the camera in the 1880’s. He invented the color film on April 15, 1935. Also, he invented black and white film in the 1880’s. Eastman invented the camera so people could remember the things they do. The things that you do may be very special to you. He also invented the camera to try different things, and to make things seem like they're alive. Also, to keep that moment forever. Eastman found a mettle box. He made the film. He also invented the “dry plate”.
That's how George Eastman invented the camera.
We classify cameras into four groups by the way they are focused. Rangefinder and viewfinder cameras have a "viewfinder" through which the picture is framed. The rangefinder differs from the viewfinder in that it has a double image created through the use of mirrors. We refer to this as a split-image. When the two images line up (are superimposed) the camera is in focus.
Twin Lens cameras have two look-alike lenses, hence the name "twin lens." The scene before the camera is actually photographed through the bottom lens while viewed through the top lens. As the picture is focused through the top lens, the bottom lens is adjusted at the same time.
The Bellows camera gets its name from the characteristic bellows. The bellows are the accordianlike body that connects the lens to the rest of the camera. But it is important to remember that it is focused on the ground (frosted) glass at the back of the camera, before the film pack (or plate) is inserted. (Not all cameras with bellows are classified as "bellows" cameras. Incidentally, these cameras may also be referred to as view cameras, not to be confused with the viewfinder type listed above.)
The Single Lens Reflex (SLR) uses a series of mirrors so that one may view the scene to be photographed through the same lens that takes the picture. When the shutter release is depressed the lower mirror snaps up, the picture is taken, and the mirror returns to its original position. (Hence, a "reflex" action.) At the time the picture is taken, the viewfinder is blackened for a split second.
Light travels in a straight line and, when white, represents the presence of all colors. We call light direct from the source incidence light, while indirect light is referred to as reflected light. Some light meters have two settings depending on the lighting situation. Can you think of some examples of each type? Since light travels in a straight line, we find that in the eye, or in a simple pinhole camera, the image will appear upside down and backwards.

Negatives, film, and developing fees, the three major complaints of today's cameras, may not be around for much longer. After more than a century of conventional photography, digital cameras are making their way into everyday life. These new high tech cameras will enable us to take rich, colorful pictures more efficiently and at lower costs than ever before. Because of these benefits, the popularity of digital cameras will soon eclipse that of conventional cameras and eventually revolutionize the way we work and capture memories. The newest line of digital cameras capture pictures with a quality that parallels film's - a feat that seemed impossible merely one year ago - and makes the future of digital cameras look very bright.
Digital cameras are similar to their mechanical counterparts, and they operate by using the same basic principles. Light from the sun (or another light source) hits an object. Light reflected from the object enters the lens of the camera, and passes through a series of optics. The light then hits a photosensitive material. In traditional cameras, the photosensitive material is film. However, in a digital camera, the light hits a charged-coupled device (CCD) sensor. This sensor, which essentially captures the image, is a multi-layered silicon chip divided into millions of tiny pixels. Each pixel of the CCD represents a point of color on the final image. The quality of the image that is captured varies directly with the number of pixels of the sensor - the more pixels, the higher the quality of the resulting image. When a pixel of the CCD is bombarded by photons (particles of light), electrons in the silicon are released. These signals are converted to a digital format, and the millions of signals are combined to form an image
Cameras are available that take as good or better quality pictures than taken by an expensive, traditional Hasselblad or a Bronica. Photos look crisp and clear, not the grainy pictures you remember seeing years ago. Instead of film, digital cameras have a memory chip. The photos can be downloaded from the camera to a computer on site. This enables you and the photographer to determine if the photos are turning out the way we want them to. If there are any problems, we see them instantly and can re-shoot the photos. Once they are downloaded, we can email them all over the world, print proofs to show friends and family, view them in the limo as you drive to the reception, even set up a slide show at your reception of the pictures you took that afternoon!
Retouching is easy and the options are endless. We can have our teeth straightened, erase wrinkles, minimize or remove a scar, cover a blemish, fix the broken fence in the background of your pictures. Digital photography enables the photographer to perfect our photos within minutes. With traditional film, retouching is arduous and requires hours in labor.
After we decide on the photos we want in your album and reprinted, our photographer simply uses a high quality printer (not the kind we can buy in office supply stores), and photo paper to print the pictures in any size we want. This reduces the need for harmful chemicals, thereby helping the environment. We also avoid the risks and waiting time of sending your negatives to a lab to be developed. Most photographers will provide you with a CD of your photos. They will usually have to be shrunk in order for the files to fit on a single disk and cannot be printed, but it is useful for emailing friends and family, or posting on your website.
