Ambrotype
The ambrotype (from grc, ἀμβροτός — “immortal”, and — “impression”) also known as a collodion positive in the UK, is a positive photograph on glass made by a variant of the wet plate collodion process. Like a print on paper, it is viewed by reflected light. Like the daguerreotype, which it replaced, and like the prints produced by a Polaroid camera, each is a unique original that could only be duplicated by using a camera to copy it. The ambrotype was introduced in the 1850s. During the 1860s it was superseded by the tintype, a similar photograph on thin black-lacquered iron, hard to distinguish from an ambrotype if under glass. Process One side of a clean glass plate was coated with a thin layer of iodized collodion, then dipped in a silver nitrate solution. The plate was exposed in the camera while still wet. Exposure times varied from five to sixty seconds or more depending on the brightness of the lighting and the speed of the camera len ...

Tintype
A tintype, also known as a melainotype or ferrotype, is a photograph made by creating a direct positive on a thin sheet of metal coated with a dark lacquer or enamel and used as the support for the photographic emulsion. Tintypes enjoyed their widest use during the 1860s and 1870s, but lesser use of the medium persisted into the early 20th century and it has been revived as a novelty and fine art form in the 21st. Tintype portraits were at first usually made in a formal photographic studio, like daguerreotypes and other early types of photographs, but later they were most commonly made by photographers working in booths or the open air at fairs and carnivals, as well as by itinerant sidewalk photographers. Because the lacquered iron support (there is no actual tin used) was resilient and did not need drying, a tintype could be photographic processing, developed and fixed and handed to the customer only a few minutes after the picture had been taken. The tintype photograph saw mor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
James Ambrose Cutting
James Ambrose Cutting (1814–1867) was an American photographer and inventor, sometimes called the inventor of the Ambrotype photographic process. He grew up in poverty on a farm in Haverhill, New Hampshire. At age 28, he invented a new type of beehive in 1842, and on the money from selling his patents moved to Boston, Massachusetts. Ambrotypes To create an ambrotype, the photographer sensitized a polished plate of glass by the wet plate collodion process and exposed the plate in a camera to produce a negative image. The wet plate collodion process was invented just a few years before by Frederick Scott Archer and widely used for glass negatives, but in an ambrotype the collodion image is used as a positive, instead of a negative. When dry, the glass plate was then backed either with black paint, metal, cloth, or paper; this black backing made light areas of the negative appear darker, turning the negative image into a positive. Some ambrotypes were made with ruby or dark green ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Collodion Process
The collodion process is an early photographic process. The collodion process, mostly synonymous with the "collodion wet plate process", requires the photographic material to be coated, sensitized, exposed, and developed within the span of about fifteen minutes, necessitating a portable darkroom for use in the field. Collodion is normally used in its wet form, but it can also be used in dry form, at the cost of greatly increased exposure time. The increased exposure time made the dry form unsuitable for the usual portraiture work of most professional photographers of the 19th century. The use of the dry form was therefore mostly confined to landscape photography and other special applications where minutes-long exposure times were tolerable. History Gustave Le Gray first theorized about the collodion process, publishing a method in 1850 that was "theoretical at best", but Frederick Scott Archer was credited with the invention of the process, which he created in 1848 and publis ...

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 ...

Collodion
Collodion is a flammable, syrupy solution of nitrocellulose in ether and alcohol. There are two basic types: flexible and non-flexible. The flexible type is often used as a surgical dressing or to hold dressings in place. When painted on the skin, collodion dries to form a flexible nitrocellulose film. While it is initially colorless, it discolors over time. Non-flexible collodion is often used in theatrical make-up. Collodion was also the basis of most wet-plate photography until it was superseded by modern gelatin emulsions. History In 1846 Louis-Nicolas Ménard and Florès Domonte discovered that cellulose nitrate could be dissolved in ether. They devised a mixture of ether (ethoxyethane) as the solvent and ethanol as a diluent that rendered cellulose nitrate into a clear gelatinous liquid. Collodion was first used medically as a dressing in 1847 by the Boston physician John Parker Maynard. The solution was dubbed "collodion" (from the Greek κολλώδης (''kollodis''), g ...

Charlotte Cushman
Charlotte Saunders Cushman (July 23, 1816 – February 18, 1876) was an American stage actress. Her voice was noted for its full contralto register, and she was able to play both male and female parts. She lived intermittently in Rome, in an expatriate colony of prominent artists and sculptors, some of whom became part of her tempestuous private life. Early life She was a descendant in the eighth generation from Pilgrim Robert Cushman, who helped organize the ''Mayflower'' voyage and brought the family name to the United States on the '' Fortune'' in 1621. Robert Cushman was a leader and a great advocate for emigration to America. He became a preacher in the colonies and was known for giving the first sermon in America. Charlotte's father, Elkanah, rose from poverty to be a successful West Indian merchant. Charlotte was a remarkably bright, sportive child, excelling over her schoolmates and developing a voice of remarkable compass and richness, with a full contralto register. Two ...

Tartan
Tartan ( gd, breacan ) is a patterned cloth consisting of criss-crossed, horizontal and vertical bands in multiple colours. Tartans originated in woven wool, but now they are made in other materials. Tartan is particularly associated with Scotland, as Scottish kilts almost always have tartan patterns. Tartan is made with alternating bands of coloured (pre-dyed) threads woven as both warp (weaving), warp and Warp and woof, weft at right angles to each other. The weft is woven in a simple twill, two over—two under the warp, advancing one thread at each pass. This pattern forms visible diagonal lines where different colours cross, which give the appearance of new colours blended from the original ones. The resulting blocks of colour repeat vertically and horizontally in a distinctive pattern of squares and lines known as a ''sett''. Tartan is often called "plaid" (particularly in North America), because in Scotland, a ''Full plaid, plaid'' is a large piece of tartan cloth, wor ...

Peninsular War
The Peninsular War (1807–1814) was the military conflict fought in the Iberian Peninsula by Spain, Portugal, and the United Kingdom against the invading and occupying forces of the First French Empire during the Napoleonic Wars. In Spain, it is considered to overlap with the Spanish War of Independence. The war started when the French and Spanish armies invaded and occupied Portugal in 1807 by transiting through Spain, and it escalated in 1808 after Napoleonic France occupied Spain, which had been its ally. Napoleon Bonaparte forced the abdications of Ferdinand VII and his father Charles IV and then installed his brother Joseph Bonaparte on the Spanish throne and promulgated the Bayonne Constitution. Most Spaniards rejected French rule and fought a bloody war to oust them. The war on the peninsula lasted until the Sixth Coalition defeated Napoleon in 1814, and is regarded as one of the first wars of national liberation. It is also significant for the emergence of larg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whaler
A whaler or whaling ship is a specialized vessel, designed or adapted for whaling: the catching or processing of whales. Terminology The term ''whaler'' is mostly historic. A handful of nations continue with industrial whaling, and one, Japan, still dedicates a single factory ship for the industry. The vessels used by aboriginal whaling communities are much smaller and are used for various purposes over the course of the year. The ''whale catcher'' was developed during the age of steam, and then driven by diesel engines throughout much of the twentieth century. It was designed with a harpoon gun mounted at its bow and was fast enough to chase and catch rorquals such as the fin whale. At first, whale catchers either brought the whales they killed to a whaling station, a settlement ashore where the carcasses could be processed, or to its factory ship anchored in a sheltered bay or inlet. With the later development of the slipway at the ship's stern, whale catchers were able ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
