In photography, a lens hood or lens shade is a device used on the front end of a lens to block the Sun or other light source (s) to prevent glare and lens flare. [1] Lens hoods may also be used to protect the lens from scratches and the elements without having to put on a lens cover. The geometry of a lens hood is dependent on three parameters ...
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.
Based on a folktale, the story follows a mustachioed cap-selling peddler (unnamed in the book, he is known as Pezzo in the sequel, Circus Caps for Sale) who wears his entire stock of caps on his head. When the peddler goes to sleep under a tree, a troupe of monkeys steal all the caps, except his own checked cap, and put them on.
Zeiss Planar. The Zeiss Planar is a photographic lens designed by Paul Rudolph at Carl Zeiss in 1896. Rudolph's original was a six-element symmetrical double Gauss lens design. While very sharp, early versions of the lens suffered from flare due to its many air-to-glass surfaces. Before the introduction of lens coating technology, the four ...
Lens hood: used on the end of a lens to block the sun or other light source to prevent glare and lens flare (see also matte box). Lens cap: covers and protects the camera lens when not in use. Lens adapter: allows the use of lenses other than those for which the camera was designed. Filter: allows artificial colors or changes light density.
Anti-reflective coatings are often used in camera lenses, giving lens elements distinctive colors. Such colors indicate the wavelength of visible light least affected by the antireflective properties of the coating. A variety of colors can be produced whose precise hue depends entirely on the thickness of the coating.
Flare star. An M-type flare star stripping away the atmosphere of its planet. A flare star is a variable star that can undergo unpredictable dramatic increases in brightness for a few minutes. It is believed that the flares on flare stars are analogous to solar flares in that they are due to the magnetic energy stored in the stars ' atmospheres.
An extended hemispherical lens is a special type of plano-convex lens, in which the lens's curved surface is a full hemisphere and the lens is much thicker than the radius of curvature. Another extreme case of a thick convex lens is a ball lens, whose shape is completely round. When used in novelty photography it is often called a "lensball".
