As of this writing in 2015,the is over 200 years every exposure. Nevertheless,Daguerre traded the right to old and the humble beginnings of pinhole imaging can even look back on the process with the french government in exchange for 3,000 years of optical evolution(see fig0).Nevertheless, it took until 1839 a patent and a life-long pension for himself and Niepce’s when optical and chemical evolution were first joined by a french partner- son. In turn the french government offered the process to ship into, what we call today traditional photography to be awarded the first anybody for free with the exception of British citizens, who patent.’From this day forward,the art of painting is dead’ a french newspaper had to pay a royalty fee. prematurely announced, but of course, that never happened,just as television never replaced the radio and digital photography never entirely replaced The the darkroom,older technologies still have enthusiastic followers, keeping The process quickly caught on and soon portrait studios established technologies alive for whatever reasons. were established all over Europe and North America to offer a likeness to whoever could afford it. Many of these images The first have survived to this day and are still in excellent shape and The credit of having made the first photograph goes to Niepce,who after two look as good now as when they were made. decades of experimenting was the first to make a stable photograph.

His approach was slightly different but ground- partner in Louis Daguerre,who continued Niepce’s research after his death breaking nonetheless His approach included coating a piece and improved image quality significantly by starting with a highly-polished of paper with light-sensitive silver nitrate and developing sheet of silver. He coated the sheet with silver iodine to make it sensitive to it in a strong alkali solution to reveal a negative image light thereby reducing exposure times from several hours to a few minutes. Then this ‘Negative was contact printed on another sheet After exposure, the silver plate with its latent image was developed in mercury of paper to create the final positive image.
