Photography and family history 1827-1850

Photography has become an intergal part of family history. This article talks about the early days of photography to better help in using photos in family history.

1827
Before photography, people, places, and events could only only be captured visually by either painting, descriptive journal entries, and using a camera obscura to trace images of life that are projected onto a piece of paper. For the average person, they could not afford paintings.

For some time, scientists has noticed that silver salts mixtures were light sensitive and would darken in light. Then, in 1827, Joseph Niepice of France, took a plate of metal, covered it with bitumen of Judah,(which was also light sensitive) stuck the plate in a camera obscura, placed it facing out his window, and took the very first photo of life. Even though it took eight hours to take the photo, it worked.

1830s
Niepice's method of photography was impractical for talking photos of people, no matter how much the remained still. So he partnered with another French man, Louis Daguerre. In 1833, Niepice died, and Dagurre kept going alone. He turned back to silver salts, this time on copper plates.

Still, photos took along time to take, around an hour or two. In those days, Dagurre and Niepice both took photos that appered on the plate with out any developing. Then in 1836, Daguerre made a surprise discovery when talking a photo and clouds covered the son, ruining the shot. Unhappy, he took the plate and put in in a cubard. The next day, he took the plate out and was startled to see an image on the plate. As it turned out, the cubbard was warm, and some murcury in the cubard turned to vapor, developing the photo. Daurre found out that the time it took to take a photo was cut drastically if one took a latent photo then developed it.
