Thomas Sutton (1819 – 19 March 1875, in Pwllheli [ citation needed ] or more likely Kensington ) was an English photographer, author, and inventor.
Pwllheli is a community and the main market town of the Llŷn Peninsula in Gwynedd, north-western Wales. It had a population of 4,076 in 2011 of whom a large proportion, 81%, are Welsh speaking. Pwllheli is the place where Plaid Cymru was founded. It is the birthplace of the Welsh poet Sir Albert Evans-Jones.
Kensington is a district in the Royal Borough of Kensington and Chelsea, West London, England.
Thomas Sutton went to school in Newington Butts and studied architecture for four years before studying at Caius College, Cambridge graduating in 1846 as the 29th wrangler. [ citation needed ] The following year, Sutton and Blanquart-Evrard founded the journal Photographic Notes, which Sutton edited for eleven years. A prolific author, Sutton wrote a number of books on the subject of photography, including the Dictionary of Photography in 1858.He opened a photographic studio in Jersey the following year under the patronage of Prince Albert. In 1855 he set up a photographic company in Jersey with business partner Louis Désiré Blanquart-Evrard that produced prints from calotype negatives.
Newington Butts is a former hamlet, now an area of the London Borough of Southwark, that gives its name to a segment of the A3 road running south-west from the Elephant and Castle junction. The road continues as Kennington Park Road leading to Kennington; a fork right is Kennington Lane, leading to Vauxhall Bridge.
At the University of Cambridge in England, a "Wrangler" is a student who gains first-class honours in the third year of the University's undergraduate degree in mathematics. The highest-scoring student is the Senior Wrangler, the second highest is the Second Wrangler, and so on. At the other end of the scale, the person who achieves the lowest exam marks while still earning a third-class honours degree is known as the wooden spoon.
Jersey, officially the Bailiwick of Jersey, is a Crown dependency located near the coast of Normandy, France. Jersey was part of the Duchy of Normandy, whose dukes went on to become kings of England from 1066. After Normandy was lost by the kings of England in the 13th century, and the ducal title surrendered to France, Jersey and the other Channel Islands remained attached to the English crown.
In 1859, Sutton developed the earliest panoramic camera with a wide-angle lens. The lens consisted of a glass sphere filled with water, which projected an image onto a curved plate. The camera was capable of capturing an image in a 120 degree arc.
In 1861, Sutton created the first single lens reflex camera.
Sutton was the photographer for James Clerk Maxwell's pioneering 1861 demonstration of colour photography. In a practical trial of a thought-experiment Maxwell had published in 1855, Sutton took three separate black-and-white photographs of a multicoloured ribbon, one through a blue filter, one through a green filter, and one through a red filter. Using three projectors equipped with similar filters, the three photographs were projected superimposed on a screen. The additive primaries variously blended to reproduce a gamut of colour. The photographic materials available to Sutton were mainly sensitive to blue light, barely sensitive to green and practically insensitive to red, so the result was only a partial success. Forty years later, adequately panchromatic plates and films had made excellent colour reproduction possible by this method, as demonstrated by the work of Sergey Prokudin-Gorsky. The principle of reproducing a full range of colour by three-colour analysis and synthesis is based on the nature of human colour vision and underlies nearly all practical chemical and electronic colour imaging technologies. Sutton's ribbon image is sometimes called the first colour photograph. There were, in fact, earlier and possibly better colour photographs made by experimenters who used a completely different, more purely chemical process, but the colours rapidly faded when exposed to light for viewing. Sutton's photographs preserved the colour information in black-and-white silver images containing no actual colouring matter, so they are very light-fast and durable and the set may reasonably be described as the first permanent colour photograph.
James Clerk Maxwell was a Scottish scientist in the field of mathematical physics. His most notable achievement was to formulate the classical theory of electromagnetic radiation, bringing together for the first time electricity, magnetism, and light as different manifestations of the same phenomenon. Maxwell's equations for electromagnetism have been called the "second great unification in physics" after the first one realised by Isaac Newton.
In color reproduction, including computer graphics and photography, the gamut, or color gamut, is a certain complete subset of colors. The most common usage refers to the subset of colors which can be accurately represented in a given circumstance, such as within a given color space or by a certain output device.
Sergey Mikhaylovich Prokudin-Gorsky was a Russian chemist and photographer. He is best known for his pioneering work in colour photography and his effort to document early 20th-century Russia.
Sutton also worked on the development of dry photographic plates.
Photography is the art, application and practice of creating durable images by recording light or other electromagnetic radiation, 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, and business, as well as its more direct uses for art, film and video production, recreational purposes, hobby, and mass communication.
A photograph is an image created by light falling on a photosensitive surface, usually photographic film or an electronic image sensor, such as a CCD or a CMOS chip. Most photographs are created using a camera, which uses a lens to focus the scene's visible wavelengths of light into a reproduction of what the human eye would see. The process and practice of creating such images is called photography. The word photograph was coined in 1839 by Sir John Herschel and is based on the Greek φῶς (phos), meaning "light," and γραφή (graphê), meaning "drawing, writing," together meaning "drawing with light."
A camera is an optical instrument to capture still images or to record moving images, which are stored in a physical medium such as in a digital system or on photographic film. A camera consists of a lens which focuses light from the scene, and a camera body which holds the image capture mechanism.
The following list comprises significant milestones in the development of photography technology.
Astrophotography is a specialized type of photography for recording photos of astronomical objects, celestial events, and areas of the night sky. The first photograph of an astronomical object was taken in 1840, but it was not until the late 19th century that advances in technology allowed for detailed stellar photography. Besides being able to record the details of extended objects such as the Moon, Sun, and planets, astrophotography has the ability to image objects invisible to the human eye such as dim stars, nebulae, and galaxies. This is done by long time exposure since both film and digital cameras can accumulate and sum light photons over these long periods of time.
Additive color, or "additive mixing", is a property of a color model that predicts the appearance of colors made by coincident component lights with distinct colors, i.e. the perceived color can be predicted by summing the numeric representations of the component colors. Modern formulations of Grassmann's Laws describe the additivity in the color perception of light mixtures in terms of algebraic equations. It is important note that additive color predicts perception and not any sort of change in the photons of light themselves. These predictions are only applicable in the limited scope of color matching experiments where viewers match small patches of uniform color isolated against a grey or black background.
Panoramic photography is a technique of photography, using specialized equipment or software, that captures images with horizontally elongated fields of view. It is sometimes known as wide format photography. The term has also been applied to a photograph that is cropped to a relatively wide aspect ratio, like the familiar letterbox format in wide-screen video.
The albumen print, also called albumen silver print, was published in January 1847 by Louis Désiré Blanquart-Evrard, and was the first commercially exploitable method of producing a photographic print on a paper base from a negative. It used the albumen found in egg whites to bind the photographic chemicals to the paper and became the dominant form of photographic positives from 1855 to the start of the 20th century, with a peak in the 1860-90 period. During the mid-19th century, the carte de visite became one of the more popular uses of the albumen method. In the 19th century, E. & H. T. Anthony & Company were the largest makers and distributors of the Albumen photographic prints and paper in the United States.
Color photography is photography that uses media capable of reproducing colors. By contrast, black-and-white (monochrome) photography records only a single channel of luminance (brightness) and uses media capable only of showing shades of gray.
In photography and cinematography, a filter is a camera accessory consisting of an optical filter that can be inserted into the optical path. The filter can be of a square or oblong shape and mounted in a holder accessory, or, more commonly, a glass or plastic disk in a metal or plastic ring frame, which can be screwed into the front of or clipped onto the camera lens.
In infrared photography, the film or image sensor used is sensitive to infrared light. The part of the spectrum used is referred to as near-infrared to distinguish it from far-infrared, which is the domain of thermal imaging. Wavelengths used for photography range from about 700 nm to about 900 nm. Film is usually sensitive to visible light too, so an infrared-passing filter is used; this lets infrared (IR) light pass through to the camera, but blocks all or most of the visible light spectrum.
In photography and optics, vignetting (, UK also ; French: vignette) is a reduction of an image's brightness or saturation toward the periphery compared to the image center. The word vignette, from the same root as vine, originally referred to a decorative border in a book. Later, the word came to be used for a photographic portrait that is clear at the center and fades off toward the edges. A similar effect is visible in photographs of projected images or videos off a projection screen, resulting in a so-called "hotspot" effect.
Chronophotography is an antique photographic technique from the Victorian era, which captures movement in several frames of print. These prints can be subsequently arranged either like animation cels or layered in a single frame. It is a predecessor to cinematography and moving film, involving a series of different cameras, originally created and used for the scientific study of movement.
The history of photography began in remote antiquity with the discovery of two critical principles: camera obscura image projection and the observation that some substances are visibly altered by exposure to light. Apart from a possibly photographic but unrecognized process used on the Turin Shroud there are no artifacts or descriptions that indicate any attempt to capture images with light sensitive materials prior to the 18th century. Around 1717 Johann Heinrich Schulze captured cut-out letters on a bottle of a light-sensitive slurry, but he apparently never thought of making the results durable. Around 1800 Thomas Wedgwood made the first reliably documented, although unsuccessful attempt at capturing camera images in permanent form. His experiments did produce detailed photograms, but Wedgwood and his associate Humphry Davy found no way to fix these images.
Ultraviolet photography is a photographic process of recording images by using light from the ultraviolet (UV) spectrum only. Images taken with ultraviolet light serve a number of scientific, medical or artistic purposes. Images may reveal deterioration of art works or structures not apparent under visible light. Diagnostic medial images may be used to detect certain skin disorders or as evidence of injury. Some animals, particularly insects, use ultraviolet wavelengths for vision; ultraviolet photography can help investigate the markings of plants that attract insects, while invisible to the unaided human eye. Ultraviolet photography of archaeological sites may reveal artifacts or traffic patterns not otherwise visible.
Louis Désiré Blanquart-Evrard was a French inventor, photographer and photo publisher. Being a cloth merchant by trade, in the 1840s he developed interest in photography and focused on technical and economical issues of mass production of photo prints.
Photographic film is a strip or sheet of transparent plastic film base coated on one side with a gelatin emulsion containing microscopically small light-sensitive silver halide crystals. The sizes and other characteristics of the crystals determine the sensitivity, contrast and resolution of the film.
Adolf Miethe was a German scientist, lens designer, photochemist, photographer, author and educator. He co-invented the first practical photographic flash and made important contributions to the progress of practical color photography.
Trichromy is the colour theory by which any colour can be reproduced solely combining the three primary colours. It relies on human trichromacy.
