Sounds like you're doing an assignment for school or something. Those are a lot of questions, and I think your answers may be best found going into a reference book or googling on the internet. Also, something that might help is typing in "how cameras work" into www.howstuffworks.com. Hope that helps.

2004, Janet Jackson showed a boob in the super bowl, an earthquake showed the power of a tsunami in India and Sumatra. Michael Jackson tried to avoid jail, Martha Stewart actually went to jail. Ray Charles died, Henri Bresson died. All hopes of Paul Dean's run for president died on his funny sounding scream/cackle/yodel clip. And gas just hit $2.00 a gallon.

The word “camera” is Latin meaning chamber or room. We think a person who loved to party invented the camera. Someone sleeping in late, had shuttered his window light-tight. The window shade must have had a tiny hole because upon arising this person saw a full color moving picture projected on the wall. A pin-hole will do this. The projected image is feeble but it can be seen OK. The idea to make a camera was a Persian or Arab scientist Abu Ali Al-Hasan, born Basra 965 ~ 1039. Soon all over Europe artist were making tents and chambers with a pin-hole. The idea was to project an image of the outside world on a piece of paper or canvas as an aid to help with drawing. The device was called a Camera Obscura. The feeble image was brightened by lenses produced by Dutch eyeglass makers. The first to chemically record an image using the Camera Obscura was the British pottery master Thomas Wedgwood. He moisten white paper with silver nitrate. He was able to get an image but the images he made needed to be kept in the dark. If brought out in the light they faded away. He also coated glass and leather with his light sensitive solution. His friend Humphry Davy descried all this in a book dated 1802. Ill health forced Wedgwood to give up. His son continued on the project but “no joy”. Joseph Necephroe Niepce of Charlon-sur Saoni in France had more success. The first permanent picture was a view from his window dated 1827. Thus Niepce gets the credit for the first photograph. His works can be viewed on line. Niepce was approached by Louis Jacques Mande Daguerre who was a scenic artist specializing in painting stage sets for the Opera and theater. Dagauerre and Niepce worked together starting in 1829. Ten years latter Niepce died and Daguerre carried on alone. By 137 Daguerre was making highly successful photographs. The daguerreotype is a copper sheet 6 ½ by 8 ½ inches. Platted one side with silver. It was placed in box with a lantern flame. Over the flame was a teaspoon filled with iodine. The heat caused iodine fumes to rise and coat the silver plate. The surface of the plate chemically became silver-iodine, a light sensitive compound. The plate was placed in the camera in the dark. The camera was aimed at a subject. The exposure was took many minutes so most shots were still-life. The exposed plate was removed from the camera in the dark. Some of the silver-iodine was reduced (split into two parts by the exposing light. Some silver-iodine was unexposed because they did not receive enough light to be reduced. The plate now contains a latten image. Next to develop the latten image. Again the plate was put back in the box with a flame. This time the teaspoon was filled with mercury. The heated mercury gave off fumes that bathed the exposed silver plate. The mercury fumes formed an image, working on the reduced silver to form an amalgam. Next the plate was fixed (rendered everlastingly by a bath in table salt water. Daguerre presented his invention to the French Academy of Science in January 1839. Want more? Just ask!
