Spherical aberrationIn optics, spherical aberration is a type of aberration found in optical systems that have elements with spherical surfaces. This phenomenon commonly affects lenses and curved mirrors, as these components are often shaped in a spherical manner for ease of manufacturing. Light rays that strike a spherical surface off-centre are refracted or reflected more or less than those that strike close to the centre.
Edward WestonEdward Henry Weston (March 24, 1886 – January 1, 1958) was an American photographer. He has been called "one of the most innovative and influential American photographers" and "one of the masters of 20th century photography." Over the course of his 40-year career Weston photographed an increasingly expansive set of subjects, including landscapes, still lifes, nudes, portraits, genre scenes, and even whimsical parodies.
Camera lensA camera lens, 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.
Julia Margaret CameronJulia Margaret Cameron (née Pattle; 11 June 1815 – 26 January 1879) was an English photographer who is considered one of the most important portraitists of the 19th century. She is known for her portraits of famous Victorians and for illustrative images depicting characters from mythology, Christianity, and literature.
Leica CameraGerman optics companyHeadquarters in Wetzlar, since 2014Leica M11Leica Camera AG () is a German manufacturer of cameras, optical lenses, photographic lenses, binoculars, and rifle scopes. The company is also active in the field of spectacle lenses, mechanical watches, smartphones and accessories, as well as in the manufacture of projectors for home cinemas. Leica developed the first 35mm cameras and later expanded into digital photography.
Bob GuccioneRobert Charles Joseph Edward Sabatini Guccione ( ; December 17, 1930 – October 20, 2010) was an American visual artist, photographer and publisher. He founded the adult magazine Penthouse in 1965. This was aimed at competing with Playboy, but with more explicit erotic content, a special style of soft focus photography, and in-depth reporting of government corruption scandals and the art world.
PictorialismPictorialism is an international style and aesthetic movement that dominated photography during the later 19th and early 20th centuries. There is no standard definition of the term, but in general it refers to a style in which the photographer has somehow manipulated what would otherwise be a straightforward photograph as a means of creating an image rather than simply recording it.
Large formatImaging format of 4×5 inches or larger Old studio camera Lens and mounting of a large format camera Comparison of 35 mm, medium format, and large format Large format photography refers to any imaging format of 9 cm × 12 cm (3.5 in × 4.7 in) or larger.Defocus aberrationQuality of an image being out of focus A photograph of Christmas lights with significant defocus aberration In optics, defocus is the aberration in which an image is simply out of focus. In general, defocus reduces the sharpness and contrast of the image. What should be sharp, high-contrast edges in a scene become gradual transitions. Fine detail in the scene is blurred or even becomes invisible.
PhotographyPhotography is the art, application, and practice of creating images by recording light, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film. It is employed in many fields of science, manufacturing (e.g., photolithography), and business, as well as its more direct uses for art, film and video production, recreational purposes, hobby, and mass communication.
Focus (optics)In geometrical optics, a focus, also called an image point, is a point where light rays originating from a point on an object converge. Although the focus is conceptually a point, physically the focus has a spatial extent, called the blur circle. This non-ideal focusing may be caused by aberrations of the imaging optics.
