North Light (architecture)
North light (in the Northern Hemisphere) is sunlight coming through a north-facing window. Because it does not come directly from the sun, it remains at a consistent angle and colour throughout the day and does not create sharp shadows. It is also cooler than direct sunlight due to the way the Earth's atmosphere scatters light via Rayleigh scattering. These properties make it the natural light of choice in certain styles of architecture, painting and photography. In addition, the cool colour of north light has been studied for its effect on our perception of art in galleries and museums. South of the equator (in the Southern Hemisphere), the same characteristics are seen in south light. Formation and properties Because the sun passes to the south of most observers in the northern hemisphere, north light is the light coming from the sky, rather than directly from the sun. This is the reason for its diffused nature, as well as why it casts softer shadows than direct sunlight and r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Hemisphere
The Northern Hemisphere is the half of Earth that is north of the equator. For other planets in the Solar System, north is defined by humans as being in the same celestial sphere, celestial hemisphere relative to the invariable plane of the Solar System as Earth's North Pole. Due to Earth's axial tilt of 23.439281°, there is a seasonal variation in the lengths of the day and night. There is also a seasonal variation in temperatures, which lags the variation in day and night. Conventionally, winter in the Northern Hemisphere is taken as the period from the December solstice (typically December 21 UTC) to the March equinox (typically March 20 UTC), while summer is taken as the period from the June solstice through to the September equinox (typically on 23 September UTC). The dates vary each year due to the difference between the calendar year and the Year#Astronomical years, astronomical year. Within the Northern Hemisphere, oceanic currents can change the weather patterns that aff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pantheon, Rome
The Pantheon (, ; ,Although the spelling ''Pantheon'' is standard in English, only ''Pantheum'' is found in classical Latin; see, for example, Pliny, ''Natural History'36.38 "Agrippas Pantheum decoravit Diogenes Atheniensis". See also ''Oxford Latin Dictionary'', s.v. "Pantheum"; ''Oxford English Dictionary'', s.v"Pantheon" "post-classical Latin ''pantheon'' a temple consecrated to all the gods (6th cent.; compare classical Latin ''pantheum'')". ) is an ancient 2nd century Roman temple and, since AD 609, a Catholic church called the Basilica of St. Mary and the Martyrs () in Rome, Italy. It is perhaps the most famous, and architecturally most influential, rotunda. The Pantheon was built on the site of an earlier temple, which had been commissioned by Marcus Vipsanius Agrippa during the reign of Augustus (27 BC – AD 14). After the original burnt down, the present building was ordered by the emperor Hadrian and probably dedicated AD 126. Its date of construction i ...

Adobe Photoshop
Adobe Photoshop is a raster graphics editor developed and published by Adobe Inc., Adobe for Microsoft Windows, Windows and macOS. It was created in 1987 by Thomas Knoll, Thomas and John Knoll. It is the most used tool for professional digital art, especially in raster graphics editing, and its name has become Generic trademark, genericised as a verb (e.g. "to photoshop an image", "photoshopping", and "photoshop contest") although Adobe disapproves of such use. Photoshop can edit and compose raster images in multiple layers and supports Mask (computing), masks, alpha compositing and several color models. Photoshop uses its own PSD and PSB file formats to support these features. In addition to raster graphics, Photoshop has limited abilities to edit or render text and vector graphics (especially through clipping path for the latter), as well as 3D graphics and video. Its feature set can be expanded by Photoshop plug-in, plug-ins; programs developed and distributed independentl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flash (photography)
A flash is a device used in photography that produces a brief burst of light (lasting around of a second) at a color temperature of about 5500 K to help illuminate a scene. The main purpose of a flash is to illuminate a dark scene. Other uses are capturing quickly moving objects or changing the quality of light. ''Flash'' refers either to the flash of light itself or to the electronic flash unit discharging the light. Most current flash units are electronic, having evolved from single-use flashbulbs and flammable powders. Modern cameras often activate flash units automatically. Flash units are commonly built directly into a camera. Some cameras allow separate flash units to be mounted via a standardized accessory mount bracket (a '' hot shoe''). In professional studio equipment, flashes may be large, standalone units, or studio strobes, powered by special battery packs or connected to mains power. They are either synchronized with the camera using a flash synchronization ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Softbox
A softbox is a type of photographic lighting modifier, one of a number of photographic soft light devices. All the various soft light types create even and diffused lightBrooks, David. ''How to Control and Use Photographic Lighting''. HPBooks, 1980, p. 54. by transmitting light through some scattering material, or by reflecting light off a second surface to diffuse the light. The best known form of reflective source is the umbrella light, where the light from the bulb is "bounced" off the inside of a metalized umbrella to create an indirect "soft" light. A softbox is an enclosure around a bulb comprising reflective side and back walls and a diffusing material at the front of the light. The sides and back of the box are lined with a bright surface – an aluminized fabric surface or an aluminum foil, to act as an efficient reflector. In some commercially available models the diffuser is removable to allow the light to be used alone as a floodlight or with an umbrella re ...

Johannes Vermeer
Johannes Vermeer ( , ; see below; also known as Jan Vermeer; October 1632 – 15 December 1675) was a Dutch painter who specialized in domestic interior scenes of middle-class life. He is considered one of the greatest painters of the Dutch Golden Age. During his lifetime, he was a moderately successful provincial genre painter, recognized in Delft and The Hague. He produced relatively few paintings, primarily earning his living as an art dealer. He was not wealthy; at his death, his wife was left in debt. Vermeer worked slowly and with great care, and frequently used very expensive pigments. He is particularly renowned for making masterful use of light in his work. "Almost all his paintings", Hans Koningsberger wrote, "are apparently set in two smallish rooms in his house in Delft; they show the same furniture and decorations in various arrangements and they often portray the same people, mostly women." The modest celebrity he enjoyed during his life gave way to obscurity ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rembrandt
Rembrandt Harmenszoon van Rijn (; ; 15 July 1606 – 4 October 1669), mononymously known as Rembrandt was a Dutch Golden Age painter, printmaker, and Drawing, draughtsman. He is generally considered one of the greatest visual artists in the history of Art of Europe, Western art.Gombrich, p. 420. It is estimated that Rembrandt's surviving works amount to about three hundred paintings, three hundred etchings and several hundred drawings. Unlike most Dutch painters of the 17th century, Rembrandt's works depict a wide range of styles and subject matter, from portrait painting, portraits and self-portraits to landscapes, genre scenes, allegorical and historical scenes, biblical and mythological subjects and animal studies. His contributions to art came in a period that historians call the Dutch Golden Age. Rembrandt never went abroad but was considerably influenced by the work of the Italian Old Masters and Bentvueghels, Dutch and Flemish artists who had studied in Italy. A ...

Infrared
Infrared (IR; sometimes called infrared light) is electromagnetic radiation (EMR) with wavelengths longer than that of visible light but shorter than microwaves. The infrared spectral band begins with the waves that are just longer than those of red light (the longest waves in the visible spectrum), so IR is invisible to the human eye. IR is generally (according to ISO, CIE) understood to include wavelengths from around to . IR is commonly divided between longer-wavelength thermal IR, emitted from terrestrial sources, and shorter-wavelength IR or near-IR, part of the solar spectrum. Longer IR wavelengths (30–100 μm) are sometimes included as part of the terahertz radiation band. Almost all black-body radiation from objects near room temperature is in the IR band. As a form of EMR, IR carries energy and momentum, exerts radiation pressure, and has properties corresponding to both those of a wave and of a particle, the photon. It was long known that fires e ...

Passive House
Passive house () is a voluntary standard for energy efficiency in a building that reduces the building's carbon footprint. Conforming to these standards results in ultra-low energy buildings that require less energy for space heating or cooling. A similar standard, MINERGIE-P, is used in Switzerland. Standards are available for residential properties, and several office buildings, schools, kindergartens and a supermarket have also been constructed to the standard. Energy efficiency is not an attachment or supplement to architectural design, but a design process that integrates with architectural design. Although it is generally applied to new buildings, it has also been used for renovations. In 2008, estimates of the number of passive house buildings around the world ranged from 15,000 to 20,000 structures. In 2016, there were approximately 60,000 such certified structures of all types worldwide. The vast majority of passive house structures have been built in German-speak ...
