When was the darkroom invente Leonardo da Vinci put the word of Camera Obscura as his writing record in the century 14th. After Louis Daguerre invented the daguerreotype process and it developed to the darkroom as worked in the tent or dark room to develop the film and papers processing in the 18 century
The camera obscura used by the ancients embodied within it the principle of the photographic camera but was lacking, as yet, in one essential ingredient : and this was a means by which a permanent record could be made of the scene projected by the lens.
Modern film photography depends for its success on the fact that chemicals, most notably the bromide and chloride of silver, are affected by the pattern of light and shade can become visible by a series of appropriate manipulations involving treating the film with chemicals. Although straightforward enough, this principle long eluded capture. Amongst the first to investigate the action of light on chemicals was the German scientist Johann Heinrich Schulze who showed in 1725 that a solution of silver nitrate and chalk held in a glass bottle darkens when placed out in the sun. Almost a century later, Thomas Wedgewood, son of Josiah Wedgewood, the founder of the pottery empire, made an interesting experiment in which leaves and other botanical specimens were placed over paper moistened with silver nitrate. When left in the sun, the border which received light darkened leaving a clear silhouette of the opaque object.
The first person to succeed in creating a permanent image using a camera obscura was a Frenchman named Joseph Nicephore
France is often regarded as the birthplace of photography.
Niepce was experimenting as early as 1816 with a camera obscura hoping to record a picture on a chemically treated stone
used bitumen spread over a pewter plate as his sensitive surface and succeeded in obtaining a positive picture in a camera obscur
. This crude photograph requiring a camera exposure of about eight hours is the world’s first photograph taken in a camera and is still in existence today.
NICEPHORE + DAGUERRE
Louis Daguerre was a contemporary of Niepce and worked in the show business, staging dioramas with
spectacular lighting effects.
Daguerre’s invention was made public in 1839 and became an instant success worldwide. The first successful portrait in America using this method was of Miss Catherine Draper; it was made in 1840
TALBOT + DAGUERRE + NICEPHORE
While the world was witnessing the marvel of the daguerreotype, a quiet revolution was taking place in England. William Henry Fox Talbot, landowner and amateur scientist, found himself fascinated with the camera obscura and began his own experiments trying to record a scene on sensitized paper
The would-be artist was William Henry Fox Talbot (1800–1877). A graduate of Trinity College, Cambridge, and a recently elected Liberal member of Parliament in the House of Commons, Talbot was a true polymath.
His intellectual curiosity of of mathematics, chemistry, astronomy, and botany; philosophy and philology; Egyptology, the classics, and art history. He had published four books and twenty-seven scholarly articles on a variety of subjects and was a fellow of the Astronomical, Linnean, and Royal Societies. ” I found that the faithless pencil had only left traces on the paper melancholy to behold.” He was quoted saying
A young English gentleman on his honeymoon sat sketching by the shore of Lake Como early in October 1833, one eye pressed close to a camera lucida.
It seemed a simple task to trace the features of the village buildings, lake, and distant mountains with his pencil. But alas, it only seemed simple, he later recalled, “for when the eye was removed from the prism—in which all looked beautiful . Talbot worked little on his invention between the sunny days of 1835 and January 1839, when the stunning news arrived that a Frenchman, Deguerre had invented a wholly different means of recording camera pictures with dazzling precision on metal plates
Talbot next tried making pictures in a camera obscura. By 1842 he had devised a satisfactory method of obtaining a negative.
Talbot spent the last twenty-five years of his life developing and perfecting an effective photogravure process.
