Photography 1800-1850 By: Jessie D. and Taylor J.
In 1801 Thomas Young suggested there were three color sensitive receptors, one sensitive to blue light, one to green and one to red. Then in 1802 Thomas Wedgwood and Sir Humphry Davy recorded by contact printing on paper coated with silver nitrate or silver chloride, silhouettes and images made upon glass, that were not permanent. http://i-eclectica.org/wordpress/wp-content/my%20images/Science/Science%202/350px-Schematic_diagram_of_the_human_eye_en.svg.png
In 1814 Joseph Nicéphore Niépce achieves the first photographic image with camera obscura - required eight hours of light exposure and later faded. 1816 - Joseph Nicephore Niepce made a crude photographic camera from a jewel box and a simple lens. With it he made a negative image. The only still existent creation called ÒheliographyÓ, by Niepce of a building and the landscape surrounding it was made in 1827. http://images.google.com/imgres?imgurl=http://bp2.blogger.com/_Yg3lYRZvzTo/R4hweFQUKJI/AAAAAAAAACw/NgewQCI0j88/s400/800px-Camera_obscura_2.jpg&imgrefurl=http://photographyhistory.blogspot.com/2008/01/cameraobscura.html&h=300&w=400&sz=16&hl=en&start=14&usg=__M9I8Z6uaQCaftS9zTH_DNtDfB94=&tbnid=zIgiuq8trrnupM:&tbnh=93&tbnw=124&prev=/images%3Fq%3Dcamera%2Bobscura%26gbv%3D2%26hl%3Den%26safe%3Dactive
1837 Daguerre’s first daguerreotype: the first image that was fixed and did not fade and needed under thirty minutes of light exposure http://images.search.yahoo.com/images/view?back=http%3A%2F%2Fimages.search.yahoo.com%2Fsearch%2Fimages%3Fp%3Dfirst%2BDaguerreotype%26fr%3Dvz-portal%26ei%3Dutf-8%26js%3D1%26x%3Dwrt&w=257&h=200&imgurl=z.about.com%2Fd%2Finventors%2F1%2F0%2F9%2FN%2Fdaguerreotype1.jpg&rurl=http%3A%2F%2Finventors.about.com%2Flibrary%2Finventors%2Fblphotography.htm&size=2.9kB&name=daguerreotype1.jpg&p=first+Daguerreotype&type=JPG&oid=f6537c013d9a8014&no=5&tt=204&sigr=11uek0kes&sigi=11i4hecbs&sigb=1332v5hmh 1839 Sir John Herschel used sodium thiosulfate, or hypo, in order to make pictures permanent. http://www.flickr.com/photos/brianritchie/313161758/

Sometimes this was called the talbotype process. The modern photographic method is based on Talbot's negative to positive principle. The Calotype process was the first negative-positive procedure making the first multiple copies possible.
In 1841Petzval mathematically calculated compound lens of f/3.6 effectively reduces Daguerreotype exposure to 1 minute. http://www.i-maps.com/hotel-locator/usa/maps/citymaps/PA/Philadelphia.png Then in 1843 the first advertisement with a photograph was made in Philadelphia. http://aeiou.iicm.tugraz.at/aeiou.encyclop.data.image.p/p292944a.jpg
1840-1844 -- 114 Travel views were issued in Paris. Daguerreotypes were taken across Europe, the Middle East, and America and were traced and transferred to copper plates for printing. http://content.answers.com/main/content/wp/en-commons/9/91/William_Fox_Talbot.jpg In 1844 Fox Talbot publishes “Pencil of Nature” the first book with photographic illustrations. http://www.thebestlinks.com/images/thumb/e/e4/250px-Louis_Daguerre.jpg
In 1837 Lois J.M. Daguerre invented the daguerreotype process. The image was recorded on a silver plate made light sensitive with iodine. The plate was then developed in mercury vapor. http://www.europepress.com/history/photography_history.htm
