World's Oldest Photograph Found?
It's time for a high tech time warp.
Set your clocks for the last years of the 18th-century, because that's when the newly identified earliest example of a photograph was taken.
The picture is of a leaf and the photographer was likely one Thomas Wedgwood of Bristol, England, who lived from 1771 to 1805. Until now, the leaf photograph was thought to have been the work of Henry Fox Talbot, who is credited with taking the world's first photographs in the 1830s.
Early photos were produced on paper treated with silver nitrate to make it light-sensitive. The image was created by laying a leaf on the light-sensitive paper and exposing it to the sun. The exposed areas of the paper darkened, leaving a silhouette.
Wedgwood and other early photographers were not able to solve the problem of over exposure, so most of their early shots were destroyed.
Most of today's digital still cameras use charge coupled devices – or CCDs – to capture images. These chips sense the light and color that comes in through a camera's lens groups and converts it into data, ultimately producing digital images. Automatic settings help us prevent our shots from being over exposed.
An art historian who was asked to assess the photograph before the auction raised the possibility of the picture being even older than originally thought.
Sotheby's was set to auction the photo, which was expected to pull in between £50-£70,000 (about $100-135,000). It's holding off on the auction until the age of the paper can be precisely determined. The auction price then is expected to skyrocket. [Source: Daily Mail]
