very first photo!

The Very First Photograph of all time

In 1827, it was Joseph Niepce who made the very first photograph with the likes of an obscura camera. Before this discovery, people generally used obscura cameras when viewing and drawing, not for photographs. Niepce's heliographics were given the name sun prints and they were a prototype for today's photograph. It was drawing with light.
Niepce did it by placing an engraving on a metallic plate which was covered with bitumen before exposing it to the light. All the white areas allowed the light to have a reaction to the chemicals on the metal plate, whereas the dark shadowy areas blocked the light. When the plate was placed in the solvent there was a visible image but gradually became invisible. The photograph was exposed to excessive light for 8 hours.
