Is a camera that takes video or still photographs, or both, digitally by recording images via an electronic image sensor.

• The purpose was to provide onboard navigation information to astronauts during missions to planets. The mosaic array periodically recorded still photos of star and planet locations during transit and when approaching a planet provided additional stadiametric information for orbiting and landing guidance. The concept included camera design elements foreshadowing the first digital camera.

History Of The Man Behind Digital Cameras

• Texas Instruments engineer Willis Adcock designed a film less camera and applied for a patent in 1972, but it is not known whether it was ever built. 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 mega pixels (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.

Types Of Digital Cameras

• Minolta Sony Kodak

How Digital Cameras Are Used Today

• Some camera types are used for making homemade crafts such as paper or digital photo memory books, creating cards, calendars, and more. Usually these cameras are of the point-and-shoot variety.A single-use camera is professional enough for advanced use, but yet they are often made simple enough for amateur photographers to use. These type of cameras are often used for taking weather photography and/or other outdoor media shots.

• They are also used for our technology today through technology such as Microsoft Words, Power Points, Window Movie Makers, and etc.

• Digital cameras can do things film cameras cannot: displaying images on a screen immediately after they are recorded, storing thousands of images on a single small memory device, recording video with sound, and deleting images to free storage space.

Advantages Of Digital Cameras

• Immediate gratification • You have the ability to immediately

deliver the image to client • Instant ISO/white balance change

from shot-to-shot • Digital media is more portable • There are no film or processing

costs• Some markets accept only digital

submissions• No scan-related costs• Digital offers improved tonal range

Disadvantages Of Cameras

• Higher initial cost • Digital cameras are not equal to

film cameras in features • Digital requires greater battery

consumption • Perception problems • Poor low-light performance• Some markets refuse digital

submissions• Digital has a steeper learning

curve • More frequent obsolescence

Overall Summary Of Digital Cameras

• WHETHER OR NOT YOU SWITCH TO DIGITAL PHOTOGRAPHY, DIGITAL IS AND WILL REMAIN A FORCE IN THE PHOTO UNIVERSE. IF YOU ARE INTERESTED IN DIGITAL, RENT OR BORROW A DIGITAL CAMERA TO GET THE FEEL OF IT. SPEND SOME TIME WITH A FRIEND WHO SHOOTS DIGITALLY AND SEE HOW THEY HANDLE THEIR DIGITAL WORKFLOW. IN TIME, I THINK THAT DIGITAL PHOTOGRAPHY WILL BE THE NORM AND THAT FILM WILL FALL FAR BEHIND. WHETHER OR NOT YOU AGREE, IT ONLY MAKES SENSE TO INVESTIGATE DIGITAL AS AN ALTERNATIVE MEDIUM. THEN YOU CAN DECIDE FOR YOURSELF IF IT IS TIME TO SWITCH.
