For the past twenty years there has been a big technological flip in retail camera's. The convention analog information has now been transformed into digital bytes. The first customer oriented digital cam was sold by Kodak and Apple during 1995. After then many makes has been introduced in the stores such as the Canon PowerShot A60, Kodak Easy Share C533, Fuji FinePix E900, Nikon Cooped S6. The new kid on the block in the category is the Canon PowerShot SD770. The biggest advantage of tiny digital cameras is that they are tiny and they could be easily carried about even in shirt pockets.
The history of cameras can be traced for centuries. The technology of camera's was discovered by Mo Ti of China. Cameras evolved from camera obscuras " Daguerreotypes - Polaroids " film cameras " disposable and finally the digital cameras. The camera obscuras was an optical device and it was primarely made for drawing It is a box with a hole in which light passed to hit a specific part of the back wall. It made a identical clone and the artist could copy the image.
The Daguerreotypes camera had coats of copper plates by mercury vapor, which made mirror like exact twin of the portrait. During 1948, Polaroid produced the instant film cameras. It used integral film with exposures which develop immediatly once the photo is snapped. in 1888 the Kodak intro'd easy use camera's with 100 film exposures. During 1959 Nikon introduced the first widely 35mm SLR cam. In 1979 Canon produced its first auto focus 35mm camera. In 1980 Kodak and Fuji film invented disposable cameras which could be expended only once. during 1995 Kodak introduced the latest digital camera to the consumers. The latest creation is the Canon SD770, which is small in mass with better photo quality and long lasting battery.
Digital cameras like any other cameras are used to take pics and vids of people, places or things. They come in varying sizes, colors, namebrands, zooms, resolutions, playbacks, prices, features and qualities. all other cams required films, and this film was then developed and pictures were made. A digital cam doesnt require film. The feature of a digital cam is the same as a conventional cam. But the variance is in way the pics are saved and the number of images stored. The pics are saved in small memory chips. These images can be erased and the memory card can be used over and over again. The number of pictures saved in a mem card depends on the memory of the card. When a pic is snapped, light is reflected on the lenses, which falls on digital sensors, which are computer chips, called CCD. The sensors are counted in mega pixel and greater the number of mega pixel, the better the picture. The PowerShot SD770 has 10 mega pixels to provide the greatest quality picture.
In a digital camera you can actually click your photo and check it right there and now. You can also think on the pics you want to keep or toss without really printing them. They are small and can be easily held. The pics kept in the memory chip of your digital cam can be uploaded into your PC. This can be accomplished by moving the pics from the memory chip to your computers hard drive or floppy disk. The digi cam comes with a USB cable which can be hooked to your PC to move the photographs. You can share your pics among your friends and family through e-mail. However, digi cams are more expensive than film cameras. They use more battery especially in cold weather. There is a limit to the size of the photo you wish to take. Poor lighting will cause grains in the picture. When new cameras are created, you might find it hard to get addons for older models.
