i love digital photography
I remember my first camera. I remember the hassle with rolls of film. I remember the bulkiness, the heaviness. Digital cameras changed my life and made me appreciate photography so much more. No longer looking awkwardly through the lens due to being left- handed. I love to be able to see right away what I take a photo of, to instantly delete bad photos and of course to take so, so many photos alomst without limit. I love tryig out all the options and settings, making it possible to be truly creative. And of course the possiblity to edit photos, to print them, to make photo books, and so on and so on. Digital photography just gives you so many creative opportunities.
what is digital photography
Digital photography uses an array of electronic photodetectors to capture the image focused by the lens, as opposed to an exposure on photographic film. The captured image is then digitized and stored as a computer file ready for digital processing, viewing, digital publishing or printing. Until the advent of such technology, photographs were made by exposing light sensitive photographic film, and used chemical photographic processing to develop and stabilize the image. By contrast, digital photographs can be displayed, printed, stored, manipulated, transmitted, and archived using digital and computer techniques, without chemical processing.
history of digital photography
The first recorded attempt at building a digital camera was in 1975 by Steven Sasson, an engineer at Eastman Kodak. It used the then-new solid-state CCD image sensor chips developed by Fairchild Semiconductor in 1973. The camera weighed 8 pounds (3.6 kg), recorded black and white images to a cassette tape, had a resolution of 0.01 megapixels (10,000 pixels), and took 23 seconds to capture its first image in December 1975. The prototype camera was a technical exercise, not intended for production.
The first true digital camera that recorded images as a computerized file was likely the Fuji DS-1P of 1988, which recorded to a 16 MB internal memory card that used a battery to keep the data in memory. This camera was never marketed internationally, and has not been confirmed to have shipped even in Japan. The first commercially available digital camera was the 1990 Dycam Model 1; it also sold as the Logitech Fotoman. It used a CCD image sensor, stored pictures digitally, and connected directly to a computer for downloading images.
The first flyby spacecraft image of Mars was taken from Mariner 4 on July 15, 1965 with a camera system designed by NASA/JPL. It used a video camera tube followed by a digitizer, rather than a mosaic of solid state sensor elements, so it was not what we usually define as a digital camera, but it produced a digital image that was stored on tape for later slow transmission back to earth.
