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.Know More
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
A camera works by using a converging, light-focusing lens to let light enter the camera box. The light creates an image by causing a chemical reaction on photo film or an electrical reaction on digital medium.Full Answer >
The time can be changed on a JVC car stereo by powering up the stereo, adjusting both the hours and minutes as needed, and selecting a.m. or p.m. on the display. After finding the locations of different buttons and settings, adjusting the time is a straightforward process.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 >
Video graphics array cameras are low-end cameras typically found on budget cell phones, but they can also be used as security cameras. Their photos are 0.3 megapixel, with video at the same quality as standard-definition television.Full Answer >
