The Cameras history and information

1. Camera Obscura - 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.In the 17th century, the modern camera came one step closer when Isaac Newton and Christian Huygens perfected the understanding of optics and the process of making high quality glass lenses.
3. Film was added by Joseph Niepce 
4. Modern cameras and older cameras still take pictures and still have some sort of film. 
5. Digital cameras use digital film which stores everything  in a computer rather than in a roll of film.
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. 
8. To freeze fast motion in pictures the camera will use higher shutter speed. 
9. Basically to get the camera ready to take the picture. 
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 cameras its set as a default and it takes the pictures when they think they the pictures need light. 

12. To much light will cause the picture to look washed out. 

13. Not enough light the picture will look to dark. 

14. a "stop" is relative measurement of light . 

15. its is 1 stop brighter in the new planet. 

16 2 stops are brighter if there are 4 suns instead of two. 

17. longer shutter more light.

18.Shorter shutter less light. 

19. You can control the aperture by setting the "Aperture Opening", also known as an F-Stop.

20. Smaller F-stops numbers = larger openings

larger openings = more light
