Michael Shor rock The chemistry of Photography Summary: Joseph-Nicephore Niepce took he word? s first photographs in 1824. Many people don? t know that he was the person who invented photography; they think that a Frenchman named Daguerre was the inventor but he got the idea from Niepce. Jacqueline Belloni, a chemist at the University of Paris-South at Orsay, is doing research on? holes? in halide ions. The problem with? holes? is that they gobble up light-generated electrons. Belloni reasoned that the solution was to dope the film. The do pant would be a negatively charged ion, like halide, so it could substitute for halide in the crystal lattice.
Instead of needing ten photons a crystal doped with formate does the job with two. A benefit to consumers will be that it will make high-speed film less grainy and better quality. Rene De Kenzer, a chemist at Agfa-Gev eart helps fund Belloni? s research, predicts A gfe will have doped films on the market within four years. Film emulsions today are a million times better at capturing photons but they still have a long way to go. 3 Things Learned: ~$10 single use camera has 10 times better resolution than today? s $1000 digital camera.
~There are 10 billion crystals in a frame of ordinary film. ~The first camera invented was a cubical wooden box about a foot on a side and the film was a tin or stone plate coated in asphalt. Response: I think this article was interesting I never realized how complicated it is to develop a photograph. I think it would be incredible to be able to see one of the first photo? s Niepce ever made.
The Essay on Ocean’s Eleven Film Casino Camera
A man who just got out of jail, got a group of eleven people together to rob a casino in Las Vegas and managed to get away with it. Stephen Soderbergh managed to get the audience to root for this bunch of thieves by using different techniques to capture the audience's attention and distract them from questioning the moral implications of the film. Furthermore, by making the crime victim a wealthy ...
