6. Auto mode will completely control flash exposure. Program just point and shoot and you control the flash.
7. It  is used to blur out the background, camera will use the fastest lens avaliable.
8. To freeze motion, camera will use the highest shutter speed possible.
9. Because you get faster camera response time,more control over focus, and encourages better composition. 
10. Disabled flash or no flash needed cause there is enough natural light.
11. Auto-Flash which mens the camera will send flash whenever it thinks it is needed.
12. Too much light and the picture will be washed out.

14. A "stop' is a relative measure of light.
15. 1 stop brighter.
16. 2 stops brighter.
17. A longer shutter speeds has more light .
18. A shorter shutter speed has less light.
19. Controls amount of light.
20. by moving it stops brighter.
