Camera History and Information

1. Inside a completely dark room, a tiny hole is created in one wall. Through the hole light is focused, and the outside scene is projected (upside down) on the opposite wall.
2. When Isaac Newton and Christian Huygens perfected the understanding of optics and the process of making high quality glass lenses.
3. He added *film* to create the first successful photograph, and the modern camera was born.
4. They both have a glass lens, a dark box and use film.
5. Digital cameras capture the images with an electronic sensor called a CCD.
6. Auto-- the camera will completely control flash and exposure. On most cameras this is labelled "auto", on others simply "A". Some cameras only have (P)rogram. 
Program-- automatic-assist, just point and shoot. Unlike full auto mode, you can usually control flash and a few other camera settings. 
7. Portrait-- To attempt to blur out the background, camera will try to use the fastest available lens setting (aperture). 
8. Sports-- To freeze motion, camera will use the highest shutter speed possible.  
9. Faster camera response time, more control over focus, and encourages better composition.
10. Disabled Flash/no flash. There are many cases where you may not want flash at all. The mood of the photograph can sometimes be more dramatic when the natural light is used.
11. Auto-Flash. In most camera modes, Auto-flash is enabled by default and will automatically fire if the camera thinks it needs more light.
12. Too much light and the picture will be washed out.
13. Not enough light and the picture will be too dark.
14. A "stop" is a relative measurement of light.
15. 1 "stop"
16. 2 "stop"
17. Longer shutter speeds = more light
18. Shorter shutter speeds = less light 
19. Before light reaches film, it must pass through an opening called an "Aperture". The aperture is like a pupil. You can control the aperture by setting the "Aperture Opening", also known as an F-Stop.
20. Larger openings = more light
