    1975 – Bryce Bayer of Kodak develops the Bayer filter mosaic pattern for CCD color image sensors. 1976 – Steadicam becomes available. 1986 – Kodak scientists invent the world's first megapixel sensor. 1987. Canon releases the first camera for its fully electronic autofocus EF lens mount, the EOS 650 [20]

  3. Infrared - Wikipedia

    en.wikipedia.org/wiki/Infrared

    Thermographic cameras detect radiation in the infrared range of the electromagnetic spectrum (roughly 9,000–14,000 nm or 9–14 μm) and produce images of that radiation. Since infrared radiation is emitted by all objects based on their temperatures, according to the black-body radiation law, thermography makes it possible to "see" one's ...

    View from the Window at Le Gras 1826 or 1827, believed to be the earliest surviving camera photograph. [1] Original (left) and colorized reoriented enhancement (right).. The history of photography began with the discovery of two critical principles: The first is camera obscura image projection, the second is the discovery that some substances are visibly altered by exposure to light [2].

  5. Ultraviolet photography - Wikipedia

    en.wikipedia.org/wiki/Ultraviolet_photography

    Ultraviolet photography is a photographic process of recording images by using radiation from the ultraviolet (UV) spectrum only. Images taken with ultraviolet radiation serve a number of scientific, medical or artistic purposes. Images may reveal deterioration of art works or structures not apparent under light.

  6. Science of photography - Wikipedia

    en.wikipedia.org/wiki/Science_of_photography

    Science of photography. The science of photography is the use of chemistry and physics in all aspects of photography. This applies to the camera, its lenses, physical operation of the camera, electronic camera internals, and the process of developing film in order to take and develop pictures properly. [1]

  7. Infrared photography - Wikipedia

    en.wikipedia.org/wiki/Infrared_photography

    Infrared photography. In infrared photography, the photographic film or image sensor used is sensitive to infrared light. The part of the spectrum used is referred to as near-infrared to distinguish it from far-infrared, which is the domain of thermal imaging. Wavelengths used for photography range from about 700 nm to about 900 nm.

  8. History of photographic lens design - Wikipedia

    en.wikipedia.org/wiki/History_of_photographic...

    Early photographic camera lenses (1800–1890) Biconvex (or double convex) lens with aperture stop in front of it. The early photographic experiments of Thomas Wedgwood, Nicéphore Niépce, Henry Fox Talbot, and Louis Daguerre all used simple single-element convex lenses. [2]: 55 These lenses were found lacking.

  9. Photographic filter - Wikipedia

    en.wikipedia.org/wiki/Photographic_filter

    Photographic filter. Four photographic filters (clockwise from top-left): an infrared hot mirror filter, a polarizing filter, and a UV filter. The larger filter is a polarizer for Cokin-style filter mounts. In photography and cinematography, a filter is a camera accessory consisting of an optical filter that can be inserted into the optical path.
