NBT News Photography Day:

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. Here is a look at photography over the years.

World Photo Day originates from the invention of the Daguerreotype, a photographic process developed by Frenchmen Louis Daguerre and Joseph Nicephore Niepce in 1837.

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.
