Most people haven't heard of World Photography Day. For photography lovers, it's just a day to come together and celebrate the awesome hobby of photography. World Photography Day has been celebrated pretty steadily for the past twenty years. The date of August 19th is chosen because that was the day the newly-invented Daguerrotype was announced to the public by the French government, in 1839. The year 1839 is unofficially the year that photography was invented.
So, for World Photography Day, throw a party and celebrate your skills! It only comes once a year!
