  2. Lens flare - Wikipedia

    en.wikipedia.org/wiki/Lens_flare

    Lens flare on Borobudur stairs to enhance the sense of ascending. A lens flare is often deliberately used to invoke a sense of drama. A lens flare is also useful when added to an artificial or modified image composition because it adds a sense of realism, implying that the image is an un-edited original photograph of a "real life" scene.

  3. Polarizing filter (photography) - Wikipedia

    en.wikipedia.org/wiki/Polarizing_filter...

    Circular polarizer/linear analyzer [1] filtering unpolarized light and then circularly polarizing the result. A polarizing filter or polarising filter (see spelling differences) is a filter that is often placed in front of a camera lens in photography in order to darken skies, manage reflections, or suppress glare from the surface of lakes or the sea.

  4. GLARE - Wikipedia

    en.wikipedia.org/wiki/GLARE

    A single sheet of Glare may be referred to using the naming convention GLARE grade - Aluminum layers / Glass fiber layers - Aluminum layer thickness. The number of aluminum layers is always one more than the number of glass fiber layers, and the aluminum layer thickness is in millimeters, which can range from 0.2 to 0.5 mm (0.0079 to 0.0197 in ...

  5. Anti-reflective coating - Wikipedia

    en.wikipedia.org/wiki/Anti-reflective_coating

    For the example of glass (n S ≈ 1.5) in air (n 0 ≈ 1.0), this optimal refractive index is n 11.225. [20] [21] The reflection loss of each interface is approximately 1.0% (with a combined loss of 2.0%), and an overall transmission T 1S T 01 of approximately 98%. Therefore, an intermediate coating between the air and glass can halve the ...

  6. Veiling glare - Wikipedia

    en.wikipedia.org/wiki/Veiling_glare

    Veiling glare in a photograph from Cassini (spacecraft) Veiling glare caused by stray light reflecting inside the camera or scattering in the lens. Veiling glare is an imperfection of performance in optical instruments (such as cameras and telescopes) arising from incoming light that strays from the normal image-forming paths, and reaches the focal plane. [1]

  7. Pattern glare - Wikipedia

    en.wikipedia.org/wiki/Pattern_glare

    Pattern glare is a form of visual discomfort [1] that arises from viewing repetitively striped patterns, such as those of op art. Instead of the patterns' appearing ...

  8. Glare (vision) - Wikipedia

    en.wikipedia.org/wiki/Glare_(vision)

    Discomfort glare is a psychological sensation caused by high brightness (or brightness contrast) within the field of view, which does not necessarily impair vision. [2] In buildings, discomfort glare can originate from small artificial lights (e.g. ceiling fixtures) that have brightnesses that are significantly greater than their surrounding.

  9. Subpixel rendering - Wikipedia

    en.wikipedia.org/wiki/Subpixel_rendering

    [clarification needed] Therefore, turning on the G and B of one pixel and the R of the next pixel to the right will produce a white dot, but it will appear to be 1/3 of a pixel to the right of the white dot that would be seen from the RGB of only the first pixel. Subpixel rendering takes advantage of this to provide three times the horizontal ...
