Louis Daguerre Fiona, Lauren, Kayleigh!

Louis Daguerre, in full Louis-Jacques-Mandé Daguerre (born November 18, 1787) French painter who invented the first practical process of photography, known as the daguerreotype. Invented in 1839.

'Sliding-box design' was most popular, these were made by opticians or the photographers themselves.

"The process of making a daguerreotype starts with a silver-plated copper plate. That plate is first buffed and polished until it looks like a mirror. Then the plate is sensitized to light over iodine and bromine in specialized, light-proof boxes.

The plate, now yellow-rose in appearance, is then transferred via a light-proof holder into a camera, where it is exposed. Originally, this exposure could take as long as fifteen minutes, but improvements to the sensitization process (adding silver halides) and better lenses eventually dropped that number below one minute.

Finally, once the plate is exposed, it’s developed or “brought out” over hot mercury, fixed by immersion in a solution of sodium thiosulfate and then washed with distilled water. The final step is to tone or gild the plate using gold chloride, yielding, as Carrillo puts it “something that is unlike any other type of photograph.”
