Google Doodle for honoring Louis Daguerre who invented the daguerreotype process of photography




By showing Special Doodle in its Home Page, Google is honoring Louis Daguerre who was a French artist and physicist, recognized for his invention of the daguerreotype process of photography. He was born on  November 18, 1787 in France. Today is his 224th birthday.


A professional scene painter for the opera with an interest in lighting effects, Daguerre began experimenting with the effects of light upon translucent paintings in the 1820s.



He invented the Daguerreotype along with Nicéphore Niépce. Louis Daguerre introduced the daguerreotype process to the public on August 19, 1839 at a meeting of the French Academy of Sciences in Paris. 

Before the daguerreotype, photography required hours of exposure and Louis Daguerre's invention reduced it to 20-30 minutes

The daguerreotype  was the first commercially successful photographic process. The daguerreotype is a direct-positive process, creating a highly detailed image on a sheet of copper plated with a thin coat of silver without the use of a negative. The process required great care. Although daguerreotypes are unique images, they could be copied by redaguerreotyping the original. Copies were also produced by lithography or engraving. Portraits based upon daguerreotypes appeared in popular periodicals and in books.



Daguerre’s Boulevard du Temple could be the first photograph to include a human being. The photo was taken by Daguerre in 1838 in Paris, and it captured a man standing alongside the road. Louis Daguerre achieve the Boulevard du Temple after exposing a chemically treated metal plate for ten minutes. Surprisingly, the person standing alongside the road was not the only person around that time. Other “human beings” were walking or riding in carriages down but they’re were moving so they didn’t show up.

The solar eclipse of July 28, 1851 is the first correctly exposed photograph of a solar eclipse, using the daguerreotype process


Watch below the YouTube Video showing many daguerreotypes.







Some Reports gives some clue about the reason behind showing this Doodle Today.


Speaking of cameras, Google is selling a new smartphone today in United Kingdom which features a five-megapixel back camera with zero-shutter lag, the Samsung Google Galaxy Nexus which features the newest version of Android’s operating system, the Ice Cream Sandwich. Coincidence? Well, maybe.

What do you think about this Doodle? Just Coincidence or Google's Business Tactics?
