Joseph Nicéphore Niépce

The earliest known permanent photograph is the View from the window at Le Gras by Nicéphore Niépce. The photograph was exposed by camera obscura on bitumen coated plate. Bitumen is sensitive to light, but not much. Eight hour exposure was needed to create the picture. That’s about 0.005 ISO in today’s standards…

Few years after making this picture Niépce teamed up with Daguerre to bring the quality to whole new level. But this photograph has started it all.

Niépce was born in France on March 7, 1765, 246 years ago. On March 7 2011, Digital Photo Calculator for iPhone will be available at substantial discount.

Happy anniversary!
