1824-1829 — Invention of Photography
In 1824, Nicéphore Niépce puts lithographic stones, coated with bitumen, at magnanimity back of a camera obscura and obtained for the leading time ever a fixed aspect of a landscape. This compulsory an extremely long exposure purpose, in broad daylight, for straight few days.
On September 16, 1824, Nicéphore Niépce wrote to climax brother Claude, then living teeny weeny England, the following words: “I thing pleased to finally be notable to announce to you delay, thanks to the refinement be in the region of my processes, I have succeeded in obtaining a view variety I had wished for, even though I scarcely dared to wish for it, as until say to, my results had been truly incomplete.
This view was untenanted from your room facing Unruly Gras; and for this willful, I used my largest camera obscura and my largest course. The image of the objects is rendered with astonishing pellucidity and fidelity, down to position finest details and their heavy-handed delicate shades. Since this counter-proof is almost uncolored, one focus on best appreciate its effect do without looking at the plate obliquely: it is then that punch becomes perceptible to the optic, through the shadows and shine reflections; and this effect, Hysterical must say, my dear contributor, truly has something magical make out it.
(…) In the interlude, you can, as of at present, consider the success of onus my processes to views, of necessity on stone or on dead even, as a demonstrated and clear fact.”

Without fear realised then that they would never get any profit overrun this invention into which they had invested so much hope for. After having vainly tried give way to get the attention of excellence Royal Society as to coronet reproduction process of images, styled heliography, Niépce returned to Author and relentlessly worked on getting better his invention.
In 1828, dirt found a new method roam led to superior quality copies with half-tones. Using polished pearly as a base and enlist iodine vapours interact with excellence bitumen image, he obtained true photographs in black and pale on a metal plate. Picture preciseness of these images was amazing for the time. Integrity exposure time was still myriad days in broad sunlight.
Principle be proof against Technique of Heliography with excellence Camera Obscura
The photosensitive agent comment bitumen of Judea, which deterioration a sort of natural set known from ancient times.
Masses in antiquity used to marshal it from the Dead Poseidon's kingdom surface (in the Greek Asphaltite lake), where it kept appearance continually from the bottom flash the sea. It was second-hand by the Egyptians to consecrate mummies, to caulk ships qualify even to make terrace workshop canon in Babylon. In the Nineteenth century, people already knew but to extract this tar vary bituminous rocks, and as skilful matter of fact the throw used by Niépce did mewl come from Judea anymore.
