In today's market there are hundreds of collecting areas available to interested parties. In the world of photography, there are many sub- categories which interest collectors. Perhaps one of the most intriguing areas is that of the daguerreotype.
Louis-Jacques-Mande Daguerre announced his invention of the daguerreotype process to the public on August 19, 1839. It remained a popular medium until 1850 when faster processes became available. A daguerreotype is a process whereby silver is plated on top of copper and is polished and shined until it is mirror-like. The plate was then sensitized in a closed box over iodine until it achieved a rose color. The plate was then held in a container which did not allow light in and then transferred to a camera. After being exposed to light, the plate was developed over hot mercury until the image appeared. Finally, the plate was soaked in a solution of sodium thiosulfate and toned with gold chloride to fix the image.
