Camera History and Information.

1. The camera obscura was the first camera, the hole acted like a lens, focusing and projecting light onto the call of the dark chamber.
2. Isaac Newton and Christian Huygens helped come a step closer to understand optics and the process of making high quality glass lenses.
3. Niepce invented a glass lens, a dark box, and film to create the modern camera.
4. The digital camera is not very different from Niepce's camera because light passes through the lens, into the camera, and exposes the film.
5. Digital cameras use an electronic sensor called a CCD to capture images.
6. With program mode, you can control the flash and other camera settings unlike auto mode, it will completely control flash and exposure.
7. The portrait mode is used to blur out the background, and it will try to use the fastest available lens setting.
8. The sports setting is used to greece motion, it uses the highest shutter speed possible.
9. The half-press is used to have a faster camera response time, helps have more control over focus, and also encourages better composition.
10.Disabled flash, this symbol means no flash. You would use this when its dark or need light.
11. Auto flash, it means the flash is automatic. Its used when it thinks it needs more light.
12. If there is too much light in your picture, the picture will be washed out.
13. If not enough light, the picture will be too dark.
14. A "stop" is a relative change in the brightness of light.
15. There is 1 stop brighter in the new planet.
16. There are 2 stops brighter if there where four suns instead of two.
17. The longer the shutter speed, the more light there is.
18. The shorter the shutter speed, the less light there is.
19. The aperture is like a pupil, it controls the "aperture opening" aka. F-Stop.
20. Smaller F- stops numbers, the larger openings. Larger opening, the more light.
