Underwater Photography The Wonders Under The Sea

History Of Photography ... The novel Giphantie (by the French Tiphaigne de la Roche, 1729–74) described what can be interpreted as photography... Early History: Development of chemical photography Monochrome process The first permanent photograph was an image produced in 1826 by the French inventor Joseph Nicéphore Niépce...

Camera ... Cameras may work with the light of the visible spectrum or with other portions of the electromagnetic spectrum. A camera generally consists of an enclosed hollow with an opening (aperture) at one end for light to enter, and a recording or viewing surface for capturing the light at the other end...

Telephoto Lens ... Telephoto lenses are sometimes broken into the further sub-types of medium telephoto: lenses covering between a 30° and 10° field of view (85mm to 135mm in 35mm film format), and super telephoto: lenses covering between 8° through less than 1° field of view (over 300mm in 35mm film format). Construction If a camera lens were to be constructed from a single lens of 500 mm focal length, then when the lens is focused on an object at infinity, the lens will be 500 mm away from the focal plane where the film or sensor is...

Photo Manipulation ... Creative retouching could be manipulation for fashion, beauty or advertising photography such as pack-shots (which could also be considered inherently technical retouching in regards to package dimensions and wrap-around factors) One of the most prominent disciplines in creative retouching is image-compositing... This kind of image composition is widely used when conventional photography would be technically too difficult or impossible to shoot on location or in studio...

Medium Format (film) ... In digital photography, medium format refers either to cameras adapted from medium format film photography uses, or to cameras making use of sensors larger than that of a 35 mm film frame... As of 2006, medium format digital photography sensors were available in sizes of up to 36 by 48 mm, with 39 million pixels for use with commonly available professional medium format cameras...

Film ... It is produced by recording photographic images with cameras, or by creating images using animation techniques or visual effects. The process of filmmaking has developed into an art form and industry. Films are cultural artifacts created by specific cultures, which reflect those cultures, and, in turn, affect them...

Stereoscopy ... Wheatstone originally used his stereoscope (a rather bulky device) with drawings because photography was not yet available, yet his original paper seems to foresee the development of a realistic imaging method:...

Fisheye Lens ... Mass-produced fisheye lenses for photography first appeared in the early 1960's and are generally used for their unique, distorted appearance...

Forensic Science ... In modern use, the term "forensics" in the place of "forensic science" can be considered correct as the term "forensic" is effectively a synonym for "legal" or "related to courts". However the term is now so closely associated with the scientific field that many dictionaries include the meaning that equates the word "forensics" with "forensic science"...

Digital Camera ... Digital cameras can do things film cameras cannot: displaying images on a screen immediately after they are recorded, storing thousands of images on a single small memory device, and deleting images to free storage space. The majority, including most compact cameras, can record moving video with sound as well as still photographs...

Holography ... The holographic recording itself is not a plain image – it consists of an apparently random structure of either varying intensity, density or profile. Overview and history The Hungarian-British physicist Dennis Gabor (Hungarian name: Gábor Dénes), was awarded the Nobel Prize in Physics in 1971 for "for his invention and development of the holographic method"...

Twin-lens Reflex Camera ... For practical purposes, all TLRs are film cameras, most often using 120 film, although there are many examples which used other formats. No general-purpose digital TLRs exist, since their heyday ended long prior to the digital era...

Environmentalism ... In Victorian Britain, an early "Back-to-Nature" movement that anticipated modern environmentalism was advocated by intellectuals such as John Ruskin, William Morris and Edward Carpenter, who were all against consumerism, pollution and other activities that were harmful to the natural world. Their ideas also inspired various proto-environmental groups in the UK, such as the Commons Preservation Society, the Kyrle Society, the Royal Society for the Protection of Birds and the Garden city movement, as well as encouraging the Socialist League and The Clarion movement to advocate measures of nature conservation...

Shutter (photography) ... Other mechanisms than the dilating aperture and the sliding curtains have been used; anything which exposes the film to light (for a specified time) will suffice. The time for which a shutter remains open (exposure time) is determined by a timing mechanism...

Camera Lens ... While in principle a simple convex lens will suffice, in practice a compound lens made up of a number of optical lens elements is required to correct (as much as possible) the many optical aberrations that arise. Some aberrations will be present in any lens system...

View Camera ... The bellows is a flexible, accordion-pleated box, which encloses the space between the lens and film, and has the ability to flex to accommodate the movements of the standards. The front standard is a board at the front of the camera which holds the lens and, usually, a shutter...

Film Crew ... Crew are distinguished from cast, the actors who appear in front of the camera or provide voices for characters in the film. Crew are also separate from producers, those who own a portion of either the film company or the film's intellectual property rights...

Photography ... But in an article published on February 25 of the same year in a German newspaper called the Vossische Zeitung, Johann von Maedler, a Berlin astronomer, had used the word photography already... The word photography derives from the Greek φωτός (phōtos), genitive of φῶς (phōs), "light" and γραφή (graphé) "representation by means of lines" or "drawing", together meaning "drawing with light"...

Digital Photography ... Until the advent of such technology, photographs were made by exposing light sensitive photographic film, and used chemical photographic processing to develop and stabilize the image. By contrast, digital photographs can be displayed, printed, stored, manipulated, transmitted, and archived using digital and computer techniques, without chemical processing...

Graphics ... Graphics can be functional or artistic. The latter can be a recorded version, such as a photograph, or an interpretation by a scientist to highlight essential features, or an artist, in which case the distinction with imaginary graphics may become blurred...

Fine Art ... Historically, the five greater fine arts were painting, sculpture, architecture, music and poetry, with minor arts including drama and dancing. Today, the fine arts commonly include the visual art and performing art forms, such as painting, sculpture, collage, decollage, assemblage, installation, calligraphy, music, dance, theatre, architecture, film, photography, conceptual art, and printmaking...
