Microsoft said they wanted not just to license the image for use as Windows XP's default wallpaper, but to buy all the rights to it. [10]: 3:37 [24] They offered O'Rear what he says is the second-largest payment ever made to a photographer for a single image; however, he signed a confidentiality agreement and cannot disclose the exact amount.
The effect is that for most lenses, the balance between the decreasing aberrations and the increasing diffraction effects of stopping down the lens means that lenses have an optimum aperture for best results, often about three stops closed down from maximum aperture, so for a lens with a maximum aperture of ƒ/2.8, ƒ/8 would be the optimum ...
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.
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.
Uncoated glasses lens (top) versus lens with anti-reflective coating. The reflection from the coated lens is tinted because the coating works better at some wavelengths than others. An antireflective , antiglare or anti-reflection ( AR ) coating is a type of optical coating applied to the surface of lenses , other optical elements, and ...
A zoom lens is a system of camera lens elements for which the focal length (and thus angle of view) can be varied, as opposed to a fixed-focal-length (FFL) lens . A true zoom lens or optical zoom lens is a type of parfocal lens , one that maintains focus when its focal length changes. [ 1 ]
In film cameras, the delay is caused by the mechanism inside the camera that opens the shutter, exposing the film.Because the process is mechanical, however, and relatively brief, shutter lag in film cameras is often only noticeable (and of any concern) to professionals.
In most cases, two thin lenses are combined, one of which has just so strong a positive aberration (under-correction, vide supra) as the other a negative; the first must be a positive lens and the second a negative lens; the powers, however: may differ, so that the desired effect of the lens is maintained. It is generally an advantage to secure ...
