    en.wikipedia.org/wiki/Hybrid_log–gamma

    The linear part of the conventional gamma curve was used to limit camera noise in low light video but is no longer needed with HDR cameras. [29] HLG is supported in Rec. 2100 with a nominal peak luminance of 1,000 cd/m 2 and a system gamma value that can be adjusted depending on background luminance. [5] [30]

  3. Digital camera modes - Wikipedia

    en.wikipedia.org/wiki/Digital_camera_modes

    Macro or close-up modes tend to direct the camera's focus to be nearer the camera. They may shrink the aperture and restrict the camera to wide-angle in an attempt to broaden the depth-of-field (to include closer objects) – this last mode of operation is often known as Super Macro. Movie mode allows a still camera to take moving pictures.

    The iPhone 7 Plus included a main 12 MP camera along with a 12 MP telephoto camera which allowed for 2x optical zoom and Portrait Mode for the first time in a smartphone. In early 2018 Huawei released a new flagship phone, the Huawei P20 Pro, with the first triple camera lens setup.

  6. List of longest smartphone telephoto lenses - Wikipedia

    en.wikipedia.org/wiki/List_of_longest_smartphone...

    This is a list of smartphones with a telephoto lens that offers a focal length (35mm equivalent) of at least 100mm or "4× optical zoom" with an imaging area equivalent to a 1/3.5″ or larger sensor. Smartphone lenses are often marketed in terms of "optical zoom" [1] relative to the phone's main camera. For example, 120mm is usually referred ...

  7. Camera lens - Wikipedia

    en.wikipedia.org/wiki/Camera_lens

    Different kinds of camera lenses, including wide angle, telephoto and speciality. A camera lens (also known as photographic lens or photographic objective) is an optical lens or assembly of lenses (compound lens) used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically.

  8. Optical resolution - Wikipedia

    en.wikipedia.org/wiki/Optical_resolution

    The ability of a lens to resolve detail is usually determined by the quality of the lens, but is ultimately limited by diffraction.Light coming from a point source in the object diffracts through the lens aperture such that it forms a diffraction pattern in the image, which has a central spot and surrounding bright rings, separated by dark nulls; this pattern is known as an Airy pattern, and ...

    So a standard 50 mm lens for 35 mm photography acts like a 50 mm standard "film" lens even on a professional digital SLR, but would act closer to a 75 mm (1.5×50 mm Nikon) or 80 mm lens (1.6×50mm Canon) on many mid-market DSLRs, and the 40-degree angle of view of a standard 50 mm lens on a film camera is equivalent to a 28–35 mm lens on ...
