G+ #Read of the Day: The Daguerreotype - The daguerreotype, an early form of photograph, was invented by Louis Daguerre in the early 19th c. The first photograph (1826) - Joseph Niepce, a French inventor and pioneer in photography, is generally credited with producing the first photograph.
Easy Peasy Fact:Following Niepcea€™s experiments, in 1829 Louis Daguerre stepped up to make some improvements on a novel idea.

Over in Connecticut, bluegrass nation has another outpost at the Strawberry Park Bluegrass Festival.A  Wea€™re impressed with any event that puts the Greencards on stage. Talbot was active from the mid-1830s, and sits alongside Louis Daguerre as one of the fathers of the medium.
Niepcea€™s photograph shows a view from the Window at Le Gras, and it only took eight hours of exposure time!The history of photography has roots in remote antiquity with the discovery of the principle of the camera obscura and the observation that some substances are visibly altered by exposure to light. Again employing the use of solvents and metal plates as a canvas, Daguerre utilized a combination of silver and iodine to make a surface more sensitive to light, thereby taking less time to develop. Half of the Limburg province of Belgium is added to the Netherlands, giving rise to a Belgian Limburg and Dutch Limburg (the latter being from September 5 joined to the German Confederation).June 3 a€“ Destruction of opium at Humen begins, casus belli for Britain to open the 3-year First Opium War against Qing dynasty China.


Bayard had just perfected the process of printing on to paper, which would come to define photography in the following century, but the French government had decided to invest instead in the daguerrotype, a process invented by his rival, Louis Daguerre. Wea€™re pleased to see that Phil Henry, our February feature artist joins Sharon Katz and the Peace Train at Susquehanna.
As half of the songwriting team that brought Slaid Cleaves to recognition, wea€™ve felt that Rod brought more grit to the songs they wrote together. We absolutely love the Guy Davis version of Dylana€™s a€?Sweetheart Like You,a€? and hope he shares that song with us. Former New Orleans cabdriver, Mem Shannon straps on his guitar and unleashes some of that Louisiana blues. The Boston Folk Festival is now the WUMB Music Fest and will be held in early June instead of mid September. While heavyweights Steve Riley and the Mamou Playboys along with Geno Delafose will keep the party going, theya€™ll have plenty of help from rock-solid talents such as Chris Ardoin and Jesse Lege.

As far as is known, nobody thought of bringing these two phenomena together to capture camera images in permanent form until around 1800, when Thomas Wedgwood made the first reliably documented although unsuccessful attempt.
It didna€™t take long for others to seize the new technology and create daguerreotypes of New York City street scenes. Daguerreotypes are sharply defined, highly reflective, one-of-a-kind photographs on silver-coated copper plates, usually packaged behind glass and kept in protective cases. Along with Del, there are his sons -- award winning players -- and monster pickers like Dave Grisman.
Wea€™ve seen Chris Thile with Punch Brothers and everyone knows Tim Oa€™Brien and Del McCoury.

There will be lots of interplay between Eric and the great guitarists assembled at Crossroads Guitar Festival. We celebrate once again with friends and heroes such as Tracy Grammer, Vance Gilbert, We're About 9, Red Molly, The Brilliant Inventions, Cheryl Wheeler, Chuck e Costa, Jimmy LaFave, Eliza Gilkyson, John Gorka and The Kennedys.Wea€™ll be holding our showcases again this year outside the Acoustic Live booth. Wea€™ve seen Chris Thile with Punch Brothers and everyone knows Tim Oa€™Brien and Del McCoury.A  Add Lyle Lovett and throw in diverse talents such as Josh Ritter, Brandi Carlisle and ita€™s a barn-burner. A daguerreotype, produced on a silver-plated copper sheet, produces a mirror image photograph of the exposed scene. The Government, which has been only too generous to Monsieur Daguerre, has said it can do nothing for Monsieur Bayard, and the poor wretch has drowned himself. John Hiatt and Levon Helm on the big side; the Duhks and Wailina€™ Jenneys a little less so (but dona€™t tell that to their fans). Chemistry student Robert Cornelius was so fascinated by the chemical process involved in Daguerrea€™s work that he sought to make some improvements himself.
We see that Ashley MacIssac is playing here, and so is his sister Lisa, half of the duo, Madison Violet.
It was commercially introduced in 1839, a date generally accepted as the birth year of practical photography.The metal-based daguerreotype process soon had some competition from the paper-based calotype negative and salt print processes invented by Henry Fox Talbot. And in 1839 Cornelius shot a self-portrait daguerrotype that some historians believe was the first modern photograph of a man ever produced.
For over two weeks in the summer of 2002, scientists and conservators at this prestigious facility subjected the artifact, its frame, and support materials to extensive and rigorous non-destructive testing. The result was a very complete scientific and technical analysis of the object, which in turn provided better criteria for its secure and permanent case design and presentation in the lobby of the newly-renovated Harry Ransom Center.The plate also received extensive attention from the photographic technicians at the Institute, who spent a day and a half with the original heliograph in their photographic studios in order to record photographically and digitally all aspects of the plate. The object was documented under all manner of scientific lights, including infrared and ultraviolet spectra. Long before the first photographs were made, Chinese philosopher Mo Ti and Greek mathematicians Aristotle and Euclid described a pinhole camera in the 5th and 4th centuries BCE.
In the 6th century CE, Byzantine mathematician Anthemius of Tralles used a type of camera obscura in his experimentsIbn al-Haytham (Alhazen) (965 in Basra a€“ c. Wilhelm Homberg described how light darkened some chemicals (photochemical effect) in 1694.


The novel Giphantie (by the French Tiphaigne de la Roche, 1729a€“74) described what could be interpreted as photography.Around the year 1800, Thomas Wedgwood made the first known attempt to capture the image in a camera obscura by means of a light-sensitive substance.
As with the bitumen process, the result appeared as a positive when it was suitably lit and viewed. A strong hot solution of common salt served to stabilize or fix the image by removing the remaining silver iodide. On 7 January 1839, this first complete practical photographic process was announced at a meeting of the French Academy of Sciences, and the news quickly spread. At first, all details of the process were withheld and specimens were shown only at Daguerre's studio, under his close supervision, to Academy members and other distinguished guests. Paper with a coating of silver iodide was exposed in the camera and developed into a translucent negative image.
Unlike a daguerreotype, which could only be copied by rephotographing it with a camera, a calotype negative could be used to make a large number of positive prints by simple contact printing. The calotype had yet another distinction compared to other early photographic processes, in that the finished product lacked fine clarity due to its translucent paper negative. This was seen as a positive attribute for portraits because it softened the appearance of the human face. Talbot patented this process,[20] which greatly limited its adoption, and spent many years pressing lawsuits against alleged infringers. He attempted to enforce a very broad interpretation of his patent, earning himself the ill will of photographers who were using the related glass-based processes later introduced by other inventors, but he was eventually defeated.
Nonetheless, Talbot's developed-out silver halide negative process is the basic technology used by chemical film cameras today.
Hippolyte Bayard had also developed a method of photography but delayed announcing it, and so was not recognized as its inventor.In 1839, John Herschel made the first glass negative, but his process was difficult to reproduce. The new formula was sold by the Platinotype Company in London as Sulpho-Pyrogallol Developer.Nineteenth-century experimentation with photographic processes frequently became proprietary.
This adaptation influenced the design of cameras for decades and is still found in use today in some professional cameras. Petersburg, Russia studio Levitsky would first propose the idea to artificially light subjects in a studio setting using electric lighting along with daylight.
In 1884 George Eastman, of Rochester, New York, developed dry gel on paper, or film, to replace the photographic plate so that a photographer no longer needed to carry boxes of plates and toxic chemicals around. Now anyone could take a photograph and leave the complex parts of the process to others, and photography became available for the mass-market in 1901 with the introduction of the Kodak Brownie.A practical means of color photography was sought from the very beginning. Results were demonstrated by Edmond Becquerel as early as 1848, but exposures lasting for hours or days were required and the captured colors were so light-sensitive they would only bear very brief inspection in dim light.The first durable color photograph was a set of three black-and-white photographs taken through red, green and blue color filters and shown superimposed by using three projectors with similar filters. It was taken by Thomas Sutton in 1861 for use in a lecture by the Scottish physicist James Clerk Maxwell, who had proposed the method in 1855.[27] The photographic emulsions then in use were insensitive to most of the spectrum, so the result was very imperfect and the demonstration was soon forgotten. Maxwell's method is now most widely known through the early 20th century work of Sergei Prokudin-Gorskii. Included were methods for viewing a set of three color-filtered black-and-white photographs in color without having to project them, and for using them to make full-color prints on paper.[28]The first widely used method of color photography was the Autochrome plate, commercially introduced in 1907. If the individual filter elements were small enough, the three primary colors would blend together in the eye and produce the same additive color synthesis as the filtered projection of three separate photographs. Autochrome plates had an integral mosaic filter layer composed of millions of dyed potato starch grains. Reversal processing was used to develop each plate into a transparent positive that could be viewed directly or projected with an ordinary projector. The mosaic filter layer absorbed about 90 percent of the light passing through, so a long exposure was required and a bright projection or viewing light was desirable.
Competing screen plate products soon appeared and film-based versions were eventually made. A complex processing operation produced complementary cyan, magenta and yellow dye images in those layers, resulting in a subtractive color image. Kirsch at the National Institute of Standards and Technology developed a binary digital version of an existing technology, the wirephoto drum scanner, so that alphanumeric characters, diagrams, photographs and other graphics could be transferred into digital computer memory.
The lab was working on the Picturephone and on the development of semiconductor bubble memory.
The essence of the design was the ability to transfer charge along the surface of a semiconductor. Michael Tompsett from Bell Labs however, who discovered that the CCD could be used as an imaging sensor.
