August 19 is observed as World Photography Day, which aims to inspire photographers across the planet to share a single photo with a simple purpose: to share their world with the world.
World Photo Day originates from the invention of the Daguerreotype, a photographic process developed by Frenchmen Louis Daguerre and Joseph Nicephore Niepce in 1837.
The first durable colour photograph was taken by Thomas Sutton in 1861. It was a set of three black-and-white photographs taken through red, green and blue filters. However, the photographic emulsions then in use were insensitive to the spectrum, so the result was very imperfect and the demonstration was soon forgotten.
On August 19, 2010 World Photo Day hosted its first global online gallery. Almost 270 photographers shared their pictures and people from over 100 countries visited the website. This marked the first official, globally reaching World Photo Day.
