the camera

1. The "camera obscura"(latin for dark room) effect is an illusion created by ancient greek and chinese philosophers. The idea is that there's a small stream of light from a box in a dark room and an outside scene is projected upside down on the opposing wall. 
2. 2. High quality glass lenses were created that moved us one step closer to the invention of the camera.
3. A glass lens, a dark box, and film
4. Light passes through the lens, through the camera and exposes the film in both modern and old cameras.
5. An electronic sensor called a CCD
6. Auto is fully automatic when it comes to settings, while program mode allows the user to control some of the settings
7. Its used for taking portraits, the background will blur, focusing on the subject 
8. Sports mode is used for taking pictures where the subject(s) are quickly moving, so the shutter speed is set high.
