Natalia Baquedano
Natalia Baquedano (1872 – 1936) was one of the pioneers of photography in Mexico. She was one of the first women to open a photographic studio, located at 6, Alcaiceria Street in Mexico City. At the time, there were 30 women photographers in Mexico, in comparison to the hundreds of women working as photographers in the United States. The Mexican historiography has considered her one of the first Mexican photographers. Shanti Lesur, Baquedano's niece great-granddaughter, has made an independent effort to rescue and study the work of this photographer. The Shanti Lesur Archive is at the moment the most complete source of original materials. During 2007, Shanti Lesur organized an exhibition about the work of this photographer in the Cuauhnahuac Regional Museum, located in the Palace of Cortes, in the city of Cuernavaca, Morelos, Mexico. As Bartra and Monroy have pointed out, the case of Baquedano is relevant since she preferred to study and work than becoming, as the great major ...

Cuauhnahuac Regional Museum
Cuernavaca (; nci-IPA, Cuauhnāhuac, kʷawˈnaːwak "near the woods", ) is the capital and largest city of the state of Morelos in Mexico. The city is located around a 90-minute drive south of Mexico City using the Federal Highway 95D. The name ''Cuernavaca'' is a euphonism derived from the Nahuatl toponym and means 'surrounded by or close to trees'. The name was Hispanicized to ''Cuernavaca''; Hernán Cortés called it ''Coadnabaced'' in his letters to Charles V, Holy Roman Emperor, and Bernal Díaz del Castillo used the name ''Cuautlavaca'' in his chronicles. The coat-of-arms of the municipality is based on the pre-Columbian pictograph emblem of the city which depicts a tree trunk () with three branches, with foliage, and four roots colored red. There is a cut in the trunk in the form of a mouth, from which emerges a speech scroll, probably representing the language Nahuatl and by extension the locative suffix , meaning 'near'. Cuernavaca has long been a favorite escape fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Porcelain
Porcelain () is a ceramic material made by heating substances, generally including materials such as kaolinite, in a kiln to temperatures between . The strength and translucence of porcelain, relative to other types of pottery, arises mainly from vitrification and formation of the mineral mullite within the body at these high temperatures. Though definitions vary, porcelain can be divided into three main categories: hard-paste, soft-paste, and bone china. The category that an object belongs to depends on the composition of the paste used to make the body of the porcelain object and the firing conditions. Porcelain slowly evolved in China and was finally achieved (depending on the definition used) at some point about 2,000 to 1,200 years ago; it slowly spread to other East Asian countries, then to Europe, and eventually to the rest of the world. Its manufacturing process is more demanding than that for earthenware and stoneware, the two other main types of pottery, and it ...

1872 Births
Year 187 ( CLXXXVII) was a common year starting on Sunday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Quintius and Aelianus (or, less frequently, year 940 '' Ab urbe condita''). The denomination 187 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Nitrocellulose
Nitrocellulose (also known as cellulose nitrate, flash paper, flash cotton, guncotton, pyroxylin and flash string, depending on form) is a highly flammable compound formed by nitrating cellulose through exposure to a mixture of nitric acid and sulfuric acid. One of its first major uses was as guncotton, a replacement for gunpowder as propellant in firearms. It was also used to replace gunpowder as a low-order explosive in mining and other applications. In the form of collodion it was also a critical component in an early photographic emulsion, the use of which revolutionized photography in the 1860s. Production The process uses a mixture of nitric acid and sulfuric acid to convert cellulose into nitrocellulose. The quality of the cellulose is important. Hemicellulose, lignin, pentosans, and mineral salts give inferior nitrocelluloses. In precise chemical terms, nitrocellulose is not a nitro compound, but a nitrate ester. The glucose repeat unit (anhydroglucose) within the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Daguerreotype
Daguerreotype (; french: daguerréotype) was the first publicly available photographic process; it was widely used during the 1840s and 1850s. "Daguerreotype" also refers to an image created through this process. Invented by Louis Daguerre and introduced worldwide in 1839, the daguerreotype was almost completely superseded by 1860 with new, less expensive processes, such as ambrotype ( collodion process), that yield more readily viewable images. There has been a revival of the daguerreotype since the late 20th century by a small number of photographers interested in making artistic use of early photographic processes. To make the image, a daguerreotypist polished a sheet of silver-plated copper to a mirror finish; treated it with fumes that made its surface light-sensitive; exposed it in a camera for as long as was judged to be necessary, which could be as little as a few seconds for brightly sunlit subjects or much longer with less intense lighting; made the resulting lat ...

Watercolor
Watercolor (American English) or watercolour (British English; see spelling differences), also ''aquarelle'' (; from Italian diminutive of Latin ''aqua'' "water"), is a painting method”Watercolor may be as old as art itself, going back to the Stone Age when early ancestors combined earth and charcoal with water to create the first wet-on-dry picture on a cave wall." London, Vladimir. The Book on Watercolor (p. 19). in which the paints are made of pigments suspended in a water-based solution. ''Watercolor'' refers to both the medium and the resulting artwork. Aquarelles painted with water-soluble colored ink instead of modern water colors are called ''aquarellum atramento'' (Latin for "aquarelle made with ink") by experts. However, this term has now tended to pass out of use. The conventional and most common ''support''—material to which the paint is applied—for watercolor paintings is watercolor paper. Other supports or substrates include stone, ivory, silk, reed, papy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Illumination (image)
Illumination is an important concept in visual arts. The illumination of the subject of a drawing or painting is a key element in creating an artistic piece, and the interplay of light and shadow is a valuable method in the artist's toolbox. The placement of the light sources can make a considerable difference in the type of message that is being presented. Multiple light sources can wash out any wrinkles in a person's face, for instance, and give a more youthful appearance. In contrast, a single light source, such as harsh daylight, can serve to highlight any texture or interesting features. Processing of illumination is an important concept in computer vision and computer graphics. See also *Chiaroscuro [Baidu] |
Silk
Silk is a natural protein fiber, some forms of which can be woven into textiles. The protein fiber of silk is composed mainly of fibroin and is produced by certain insect larvae to form cocoons. The best-known silk is obtained from the cocoons of the larvae of the mulberry silkworm ''Bombyx mori'' reared in captivity (sericulture). The shimmering appearance of silk is due to the triangular prism-like structure of the silk fibre, which allows silk cloth to refract incoming light at different angles, thus producing different colors. Silk is produced by several insects; but, generally, only the silk of moth caterpillars has been used for textile manufacturing. There has been some research into other types of silk, which differ at the molecular level. Silk is mainly produced by the larvae of insects undergoing complete metamorphosis, but some insects, such as webspinners and raspy crickets, produce silk throughout their lives. Silk production also occurs in hymenoptera ( bee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palace Of Cortes
A palace is a grand residence, especially a royal residence, or the home of a head of state or some other high-ranking dignitary, such as a bishop or archbishop. The word is derived from the Latin name palātium, for Palatine Hill in Rome which housed the Roman Empire, Imperial residences. Most European languages have a version of the term (''palais'', ''palazzo'', ''palacio'', etc.), and many use it for a wider range of buildings than English. In many parts of Europe, the equivalent term is also applied to large private houses in cities, especially of the aristocracy; often the term for a large country house is different. Many historic palaces are now put to other uses such as parliaments, museums, hotels, or office buildings. The word is also sometimes used to describe a lavishly ornate building used for public entertainment or exhibitions such as a movie palace. A palace is distinguished from a castle while the latter clearly is fortified or has the style of a fortification ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
