In optics, an aperture is a hole or an opening through which light travels.
Apodization is an optical filtering technique, and its literal translation is "removing the foot".
In photography, bokeh (— also sometimes pronounced as) is the aesthetic quality of the blur produced in the out-of-focus parts of an image produced by a lens.
A camera lens (also known as photographic lens or photographic objective) is an optical lens or assembly of lenses 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.
In optics, a circle of confusion is an optical spot caused by a cone of light rays from a lens not coming to a perfect focus when imaging a point source.
Désiré Charles Emanuel van Monckhoven (1834–1882) was a Belgian chemist, physicist, and photographic researcher.
In optics, particularly as it relates to film and photography, the optical phenomenon known as depth of field (DOF), is the distance about the Plane of Focus (POF) where objects appear acceptably sharp in an image.
Diffraction spikes are lines radiating from bright light sources in photographs and in vision.
Ernst Karl Abbe HonFRMS (23 January 1840 – 14 January 1905) was a German physicist, optical scientist, entrepreneur, and social reformer.
The f-number of an optical system (such as a camera lens) is the ratio of the system's focal length to the diameter of the entrance pupil.
The Fujinon XF 56mm F1.2 R is an interchangeable camera lens announced by Fujifilm on January 6, 2014.
In humans and most mammals and birds, the iris (plural: irides or irises) is a thin, circular structure in the eye, responsible for controlling the diameter and size of the pupil and thus the amount of light reaching the retina.
John Waterhouse (3 August 1806 – 13 February 1879) was a British astronomer and meteorologist who invented Waterhouse stops.
A lens is a transmissive optical device that focuses or disperses a light beam by means of refraction.
Leonhard Euler (Swiss Standard German:; German Standard German:; 15 April 170718 September 1783) was a Swiss mathematician, physicist, astronomer, logician and engineer, who made important and influential discoveries in many branches of mathematics, such as infinitesimal calculus and graph theory, while also making pioneering contributions to several branches such as topology and analytic number theory.
was a Japanese manufacturer of cameras, camera accessories, photocopiers, fax machines, and laser printers.
In photography and optics, a neutral-density filter, or ND filter, is a filter that reduces or modifies the intensity of all wavelengths, or colors, of light equally, giving no changes in hue of color rendition.
Joseph Nicéphore Niépce (7 March 1765 – 5 July 1833) was a French inventor, now usually credited as the inventor of photography and a pioneer in that field.
The Olympus XA was a 35 mm rangefinder camera built by Olympus of Japan.
An optical axis is a line along which there is some degree of rotational symmetry in an optical system such as a camera lens or microscope.
Optics is the branch of physics which involves the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it.
A point-and-shoot camera, also known as compact camera, is a still camera designed primarily for simple operation.
In elementary geometry, a polygon is a plane figure that is bounded by a finite chain of straight line segments closing in a loop to form a closed polygonal chain or circuit.
The Rodenstock Imagon is an achromat doublet photographic lens design uncorrected for spherical aberration used together with diffusion discs ("sink strainers") called sieve aperture (in German).
The Royal Microscopical Society (RMS) is a learned society for the promotion of microscopy. It was founded in 1839 as the Microscopical Society of London making it the oldest organisation of its kind in the world. In 1866, the society gained its royal charter and took its current name. Founded as a society of amateurs, its membership consists of individuals of all skill levels in numerous related fields from throughout the world. Every year since 1852, the society has published its own scientific journal, the Journal of Microscopy, which contains peer-reviewed papers and book reviews. The society is a registered charity that is dedicated to advancing science, developing careers and supporting wider understanding of science and microscopy through its Outreach activities. Probably the society's greatest contribution is its standardised 3x1 inches microscope glass slides in 1840, which are still the most widely used size today and known as the "RMS standard". The Royal Microscopical Society is a member of the Foundation for Science and Technology, the Biosciences Federation, the European Microscopy Society and the International Federation of Societies for Microscopy.
Rudolf Kingslake (born Rudolf Klickmann, August 28, 1903 – February 28, 2003)http://www.osa-opn.org/Content/ViewFile.aspx?id.
In photography, a shutter is a device that allows light to pass for a determined period, exposing photographic film or a light-sensitive electronic sensor to light in order to capture a permanent image of a scene.
The Smooth Trans Focus (STF) technology in photographic lenses uses an apodization filter to realize notably smooth bokeh with rounded out-of-focus highlights in both the foreground and background.
In photography, soft focus is a lens flaw, in which the lens forms images that are blurred due to spherical aberration.
is a Japanese multinational conglomerate corporation headquartered in Kōnan, Minato, Tokyo.
Valbray is an independent Swiss watch company co-founded by Côme de Valbray and Olga Corsini in 2009.
The Waterhouse stop or Waterhouse diaphragm is an interchangeable diaphragm with an aperture (hole) for controlling the entry of light into a camera.
