So tonight is the first photography class. Yay! My friend joined with me (although I think he already has the skills). Anyway, the first class is kind of not that interesting: the instructor briefly went through the history of photography, and then introduced the darkroom. Here's a synopsis of the history:

1. Joseph Nicephore Niepce took the first photograph in the world in 1826, in which the exposure took 8 hours to finish (you can see sunlight on both pillars).




2. The theory of pin hole camera was discovered a long time ago, however it took 900 years to find a way to capture the image and fix it.

3. And then 11 years later, Louis Jacques Mande Dagurre did something great, which he did the exposure on mercury papers! The exposure time was dramatically shorten to just several minutes. The result was much crisp and sharp:



4. And then this guy William Henry Fox Talbot presented some papers to the royal academy or something like that, and people started to call him the father of photography (by this time... my head started swimming...)

5. The last name I heard in the class was George Eastman, and my notes said that he brought handheld camera to the world. The shutter speed of the camera can go up to 1/25 seconds!


Boring stuffs, wasn't it :P
