Photography

Before photography was created, people already knew the principles of how it eventually got to work. They could process the image on the wall or piece of paper, however no printing was possible at the time as preserving light turned out to be a lot harder task than projecting it. The instrument that people used for processing pictures was called the Camera Obscura (which is Latin for the Dark Room) and it was around for a few centuries before photography came along.

The first photo picture was taken in 1825 by a French inventor Joseph Niepce. It depicts a view from the window at Le Gras. There is little merit in this picture other than the fact that it is the first photograph taken and preserved.

first glass negative as opposed to metal.

Finally, after decades of refinements and improvements, the mass use of cameras began with Eastman's Kodak's camera. It went on to the market in 1888 with the slogan "You press the button, we do the rest".

Professor J. Schulze mixes chalk, nitric acid, and silver in a flask; notices darkening on side of flask exposed to sunlight. Accidental creation of the first photo-sensitive compound.

Thomas Wedgwood makes "sun pictures" by placing opaque objects on leather treated with silver nitrate; resulting images deteriorated rapidly, however, if displayed under light stronger than from candles.

Henry Fox Talbot creates permanent (negative) images using paper soaked in silver chloride and fixed with a salt solution. Talbot created positive images by contact printing onto another sheet of paper.

Louis Daguerre creates images on silver-plated copper, coated with silver iodide and "developed" with warmed mercury; Daguerre is awarded a state pension by the French government in exchange for publication of methods and the rights by other French citizens to use the Daguerreotype process.
