Claude Glass
A Claude glass (or black mirror) is a small mirror, slightly wikt:convex, convex in shape, with its surface tinted a dark colour. Bound up like a pocket-book or in a carrying case, Claude glasses were used by artists, travelers and connoisseurs of landscape and landscape painting. Claude glasses have the effect of reducing and simplifying the colour and tonal range of scenes and scenery to give them a painterly quality. The user would turn their back on the scene to observe the framed view through the tinted mirror — in a sort of pre-photographic lens — which added the picturesque aesthetic of a subtle gradation of tones. History Poet Thomas Gray's ''Journal of his Tour in the Lake District'', published in 1775, popularized the use of the Claude mirror, sometimes referred to as a "Gray glass" around that time. On one sightseeing trip, Gray was so intent on his glass that he fell backward into "a dirty lane" and broke his knuckles; he later remarked how he kept the glass ope ...

Mary Colter
Mary Elizabeth Jane Colter (April 4, 1869 – January 8, 1958) was an American architect and designer. She was one of the very few female American architects in her day. She was the designer of many landmark buildings and spaces for the Fred Harvey Company and the Santa Fe Railroad, notably in Grand Canyon National Park. Her work had enormous influence as she helped to create a style, blending Spanish Colonial Revival and Mission Revival architecture with Native American motifs and Rustic elements, that became popular throughout the Southwest. Colter was a perfectionist, who spent a lifetime advocating and defending her aesthetic vision in a largely male-dominated field. Early life and education Mary Colter was born in Pittsburgh, Pennsylvania to Irish immigrants William and Rebecca Crozier Colter. Her family moved to Colorado and Texas before settling down in St. Paul, Minnesota, the town she considered to be her home, when Mary was eleven. In 1880, the town of St. Paul was ...

Drawing Aids
Drawing is a Visual arts, visual art that uses an instrument to mark paper or another two-dimensional surface, or a digital representation of such. Traditionally, the instruments used to make a drawing include pencils, crayons, and ink pens, sometimes in combination. More modern tools include Stylus (computing), computer styluses with graphics tablets and gamepads in Virtual reality, VR drawing software. A drawing instrument releases a small amount of material onto a surface, leaving a visible mark. The most common support for drawing is paper, although other materials, such as Paperboard, cardboard, vellum, wood, plastic, leather, canvas, and Lumber, board, have been used. Temporary drawings may be made on a blackboard or whiteboard. Drawing has been a popular and fundamental means of public expression throughout human history. It is one of the simplest and most efficient means of communicating ideas. The wide availability of drawing instruments makes drawing one of the most comm ...

Camera Obscura
A camera obscura (; ) is the natural phenomenon in which the rays of light passing through a aperture, small hole into a dark space form an image where they strike a surface, resulting in an inverted (upside down) and reversed (left to right) projector, projection of the view outside. ''Camera obscura'' can also refer to analogous constructions such as a darkened room, box or tent in which an exterior image is projected inside or onto a translucent screen viewed from outside. ''Camera obscuras'' with a lens in the opening have been used since the second half of the 16th century and became popular as aids for drawing and painting. The technology was developed further into the photographic camera in the first half of the 19th century, when ''camera obscura'' boxes were used to exposure (photography), expose photosensitivity, light-sensitive materials to the projected image. The image (or the principle of its projection) of a lensless ''camera obscura'' is also referred to as a " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Camera Lucida
A ''camera lucida'' is an optical device used as a drawing aid by artists and microscopy, microscopists. It projects an optics, optical superimposition of the subject being viewed onto the surface upon which the artist is drawing. The artist sees both scene and drawing surface simultaneously, as in a photographic double exposure. This allows the artist to duplicate key points of the scene on the drawing surface, thus aiding in the accurate rendering of perspective. History The ''camera lucida'' was patented in 1806 by the English chemist William Hyde Wollaston. The basic optics were described 200 years earlier by the German astronomer Johannes Kepler in his ''Dioptrice'' (1611), but there is no evidence he constructed a working ''camera lucida''. There is also evidence to suggest that the Elizabethan spy Arthur Gregory's 1596 "perspective box" operated on at least highly similar principles to the later ''camera lucida'', but the secretive nature of his work and fear of rivals ...

Grand Canyon
The Grand Canyon is a steep-sided canyon carved by the Colorado River in Arizona, United States. The Grand Canyon is long, up to wide and attains a depth of over a mile (). The canyon and adjacent rim are contained within Grand Canyon National Park, the Kaibab National Forest, Grand Canyon–Parashant National Monument, the Hualapai, Hualapai Indian Reservation, the Havasupai Indian Reservation and the Navajo Nation. President Theodore Roosevelt was a major proponent of the preservation of the Grand Canyon area and visited it on numerous occasions to hunt and enjoy the scenery. Nearly two billion years of Earth's geological history have been exposed as the Colorado River and its tributaries cut their Stream channel, channels through layer after layer of rock while the Colorado Plateau was Tectonic uplift, uplifted.

Desert View Watchtower
Desert View Watchtower, also known as the Indian Watchtower at Desert View, is a -high stone building located on the South Rim of the Grand Canyon within Grand Canyon National Park in Arizona, United States. The tower is located at Desert View, more than to the east of the main developed area at Grand Canyon Village, toward the east entrance to the park. The four-story structure, completed in 1932, was designed by American architect Mary Colter, an employee of the Fred Harvey Company who also created and designed many other buildings in the Grand Canyon vicinity including Hermit's Rest and the Lookout Studio. The interior contains murals by Fred Kabotie. Description The watchtower was the last of the series of Mary Colter-designed visitor concession structures at the Grand Canyon until her renovation of the Bright Angel Lodge in 1935. The tower was designed to resemble an Ancestral Puebloan watchtower, but its size dwarfs any known Pueblan-built tower. The closest prototyp ...

Claude Lorrain
Claude Lorrain (; born Claude Gellée , called ''le Lorrain'' in French; traditionally just Claude in English; c. 1600 – 23 November 1682) was a French painter, draughtsman and etcher of the Baroque era. He spent most of his life in Italy, and is one of the earliest significant artists, aside from his contemporaries in Dutch Golden Age painting, to concentrate on landscape painting. His landscapes often transitioned into the more prestigious genre of history paintings by addition of a few small figures, typically representing a scene from the Bible or classical mythology. By the end of the 1630s he was established as the leading landscapist in Italy, and enjoyed large fees for his work. His landscapes gradually became larger, but with fewer figures, more carefully painted, and produced at a lower rate.Kitson, 6 He was not generally an innovator in landscape painting, except in introducing the sun and streaming sunlight into many paintings, which had been rare before ...
