Across 1,000 years, cameras and camera-related technologies shifted from the camera obscura, or pinhole camera, through cameras that used developmental media to the modern digital camera. The digital revolution, according to Evolution of Digital Cameras, began in the 1960s with the coding of signals into the 1's and 0's used by computers. Twenty years later, Kodak pioneered the first digital camera, which has been consistently improved since then.Continue Reading
According to History of Photography and the Camera, Ibn Al-Haytham invented the first pin hole camera in approximately 1000 AD. Later, this became known as a camera obscura and was used by artists in sketching images. Images from the pinhole camera were not preserved because these cameras did not use any kind of light-sensitive media to record these images.
The use of light-sensitive media began in the 19th century, and photographers rapidly explored different ways to create photographs. Joseph Nicephore Niepce used bitumen on a plate to allow the sun to engrave the image in his camera obscura. Soon this process was improved by Daguerre, who invented the daguerreotype. Across the next 75 years, cameras changed as a result of the different types of media used.
Cameras moved away from requiring sunlight through the invention first of flash powder and later the flashbulb. Over time, lenses improved and diversified. George Eastman insured that ordinary people could have access to taking pictures through his invention of the Kodak camera, which came complete with film. After the film was used, camera owners mailed back the camera to Kodak and soon received prints and a refilled camera.Learn more about Technology
Transferring pictures from a digital camera to a computer requires either a USB cord that attaches to both the camera and the computer or a memory card that is removed from the camera and fits into an available slot in the computer or into a memory card reader that attaches to the computer. Some laptops and desktop computers are equipped with built-in memory card slots, making transfers easy to do without connection cables or wearing down the camera's battery.Full Answer >
A DSLR (digital single lens reflex) camera is a more advanced type of digital camera that uses mirrors to reflect the image into a viewfinder. When the shutter release button is pushed, the shutter opens and the mirror moves out of the way to allow light to pass through the lens.Full Answer >
Collectible camera models include 1974 to 1976 SL2 Leicaflex cameras, Kodak's Brownie models, the original Model A Leica, and Polaroid's Land Camera Model 95. The German-made 35 millimeter Leicaflex cameras have full-area matte focusing screens with central split-image rangefinders.Full Answer >
Wi-Fi cameras work by connecting to the Internet to upload pictures to a remote location, thereby saving digital storage space on the camera itself. These cameras have a switch that connects equipment to a Wi-Fi hotspot, and then sends the photographs to another piece of hardware through the Internet connection. Some Wi-Fi hotspots require login information, while others connect to the camera automatically.Full Answer >
