John Waterhouse (astronomer)
John Waterhouse (3 August 1806 – 13 February 1879) was a British astronomer and meteorologist who invented Waterhouse stops. ] He was born at Well Head House in Halifax, Yorkshire the eldest son of John and Grace Elizabeth (née Rawson) Waterhouse. Well Head had extensive gardens with greenhouses and a staff of 6 gardeners. They cultivated exotic ferns, including a Leptopteris, todea superba which Waterhouse had imported from New Zealand in 1860 and which is now at Kew Gardens. At the house, he built an observatory and meteorological station. Louis John Crossley studied at his laboratory. In 1834 he was President of the Halifax Mechanics' Institute. In the same year he was elected as a Fellow of the Royal Society. He was also a Fellow of the Royal Astronomical Society. In 1839 he travelled around the world for health reasons. Over a period of 8 years (1866–1873), he made detailed observations of the weather and of the night skies from Well Head, which he published in 187 ...

Waterhouse Stop
The Waterhouse stop or Waterhouse diaphragm is an interchangeable diaphragm with an aperture (hole) for controlling the entry of light into a camera. A thin piece of metal (the diaphragm) is drilled with a hole (the aperture); a set of these with varying hole sizes makes up a set of Waterhouse stops, corresponding to what today we call f-stops or f-numbers. Photographic lens makers provided slots in lens barrels for the insertion of the chosen stop. This apparatus was invented by the pioneering 19th-century photographer John Waterhouse of Halifax in 1858. It has also been reported to have been independently invented by Mr. H. R. Smyth, and described by Waterhouse as early as 1856. The innovation was quickly put to use due to its convenience: "Aperture openings were at first controlled by unscrewing the lens and inserting stops of the appropriate size between the lens components, though after 1858 photographers used the more convenient Waterhouse stops which eliminated unscrew ...

West Riding Of Yorkshire
The West Riding of Yorkshire is one of three historic subdivisions of Yorkshire, England. From 1889 to 1974 the administrative county County of York, West Riding (the area under the control of West Riding County Council), abbreviated County of York (WR), was based closely on the historic boundaries. The lieutenancy at that time included the City of York and as such was named West Riding of the County of York and the County of the City of York. Its boundaries roughly correspond to the present ceremonial counties of West Yorkshire, South Yorkshire and the Craven, Harrogate and Selby districts of North Yorkshire, along with smaller parts in Lancashire (for example, the parishes of Barnoldswick, Bracewell, Brogden and Salterforth became part of the Pendle district of Lancashire and the parishes of Great Mitton, Newsholme and Bowland Forest Low became part of the Ribble Valley district also in Lancashire), Cumbria, Greater Manchester and, since 1996, the unitary East Riding of ...

19th-century British Inventors
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under colonial rule. It was also marked by the collapse of the large S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Photographers From Yorkshire
A photographer (the Greek φῶς (''phos''), meaning "light", and γραφή (''graphê''), meaning "drawing, writing", together meaning "drawing with light") is a person who makes photographs. Duties and types of photographers As in other arts, the definitions of amateur and professional are not entirely categorical. An ''amateur photographer'' takes snapshots for pleasure to remember events, places or friends with no intention of selling the images to others. A ''professional photographer'' is likely to take photographs for a session and image purchase fee, by salary or through the display, resale or use of those photographs. A professional photographer may be an employee, for example of a newspaper, or may contract to cover a particular planned event such as a wedding or graduation, or to illustrate an advertisement. Others, like fine art photographers, are freelancers, first making an image and then licensing or making printed copies of it for sale or display. Some ...

People From Halifax, West Yorkshire
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

Photographic Print Toning
In photography, toning is a method of altering the color of black-and-white photographs. In analog photography, it is a chemical process carried out on metal salt-based prints, such as silver prints, iron-based prints (cyanotype or Van Dyke brown), or platinum or palladium prints. This darkroom process cannot be performed with a color photograph. The effects of this process can be emulated with software in digital photography. Sepia is considered a form of black-and-white or monochrome photography. Chemical toning Most toners work by replacing the metallic silver in the emulsion with a silver compound, such as silver sulfide (Ag2S) in the case of sepia toning. The compound may be more stable than metallic silver and may also have a different color or tone. Different toning processes give different colors to the final print. In some cases, the printer may choose to tone some parts of a print more than others. Toner also can increase the range of shades visible in a print witho ...
