Eastman Kodak Company, commonly known as Kodak, is an American multinational imaging and photographic equipment, materials and services company headquartered in Rochester, New York, United States and incorporated in New Jersey. It was founded by George Eastman in 1888.
Kodak is best known for photographic film products. During most of the 20th century Kodak held a dominant position in photographic film, and in 1976 had a 90% market share of photographic film sales in the United States. The company's ubiquity was such that its tagline "Kodak moment" entered the common lexicon to describe a personal event that demanded to be recorded for posterity.
Kodak began to struggle financially in the late 1990s as a result of the decline in sales of photographic film and its slowness in transitioning to digital photography, despite having invented the core technology used in current digital cameras. 2007 was the most recent year in which the company made a profit. As part of a turnaround strategy, Kodak focused on digital photography and digital printing and attempted to generate revenues through aggressive patent litigation. In January 2012, Kodak filed for Chapter 11 bankruptcy protection. In February 2012, Kodak announced that it would cease making digital cameras, pocket video cameras and digital picture frames and focus on the corporate digital imaging market. In August 2012, Kodak announced the intention to sell its photographic film (excluding motion picture film), commercial scanners and kiosk operations as a measure to emerge from bankruptcy. In January 2013, a court approved financing for the company to emerge from bankruptcy by mid 2013.
A stereo camera is a type of camera with two or more lenses with a separate image sensor or film frame for each lens. This allows the camera to simulate human binocular vision, and therefore gives it the ability to capture three-dimensional images, a process known as stereo photography. Stereo cameras may be used for making stereoviews and 3D pictures for movies, or for range imaging. The distance between the lenses in a typical stereo camera (the intra-axial distance) is about the distance between one's eyes (known as the intra-ocular distance) and is about 6.35 cm, though a longer base line (greater inter-camera distance) produces more extreme 3-dimensionality.
3D pictures following the theory behind stereo cameras can also be made more inexpensively by taking two pictures with the same camera, but moving the camera a few inches either left or right. If the image is edited so that each eye sees a different image, then the image will appear to be 3D. This method has problems with objects moving in the different views, though works well with still life.
Stereo cameras are sometimes mounted in cars to detect the lane's width and the proximity of an object on the road.
Not all two-lens cameras are used for taking stereoscopic photos. A twin-lens reflex camera uses one lens to image to a focusing/composition screen and the other to capture the image on film. These are usually in a vertical configuration. Examples include would be a vintage Rolleiflex or a modern twin lens like a Mamiya C330.
