  4. Chromatic aberration - Wikipedia

    en.wikipedia.org/wiki/Chromatic_aberration

    Since the focal length of the lens varies with the color of the light different colors of light are brought to focus at different distances from the lens or with different levels of magnification. Chromatic aberration manifests itself as "fringes" of color along boundaries that separate dark and bright parts of the image.

    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.

  6. Optical aberration - Wikipedia

    en.wikipedia.org/wiki/Optical_aberration

    1: Imaging by a lens with chromatic aberration. 2: A lens with less chromatic aberration. In optics, aberration is a property of optical systems, such as lenses and mirrors, that causes the image created by the optical system to not be a faithful reproduction of the object being observed. Aberrations cause the image formed by a lens to be ...

    A lens accessory that fits between the lens and camera body and extends the focal length of the lens, often by 1.4x or 2x, at the cost of reduced light, decreased image quality, and slower autofocus. TCA: Transverse (lateral) chromatic aberration or lateral colour. Colour fringes that worsen the further the image point is from the optical axis ...

    The type of lens being designed is significant in setting the key parameters. Prime lens - a photographic lens whose focal length is fixed, as opposed to a zoom lens, or that is the primary lens in a combination lens system. Zoom lenses - variable focal length lenses. Zoom lenses cover a range of focal lengths by utilising movable elements ...
