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 ....!
