Behind the history of world photo day

world photo day

Every year of 19th august were  celebrated as world photo day all over the world, in 13th century innovators were start attempting  to capturing the moment use the light , that time principle of the camera obscura and the observation that some substances are visibly altered by exposure to light were discovered.
 As far as is known, nobody thought of bringing these two phenomena together to capture camera images in permanent form until around 1800
In the mid-1820s, Nicéphore Niépce succeeded, but several days of exposure in the camera were required and the earliest results were very crude although print stay  for very few hours  . Niépce's associate Louis Daguerre went on to develop the daguerreotype process, the first publicly announced photographic process, which required only minutes of exposure in the camera and produced clear, finely detailed results. It was commercially introduced in 1839, a date generally accepted as the birth year of practical photography,   In 1826, Nicèphore Nièpce captured the earliest known permanent photograph known as 'View from the Window at Le Gras' using a process called Heliography. On January 9, 1839 French Academy of Sciences announced the daguerreotype process. A few months later, on August 19, 1839, the French government purchased the patent and announced the invention as a gift "Free to the World"


To remember this fact world photo day were celebrated every year ....!
