The Camera

1. The "camera obscura" effect was the first camera. It is achieved by creating a whole in the wall, which acts like a lens, then focusing and projecting the light onto the wall of the dark room.

2. During the 17th Century, the understanding of optics and the process of making high quality glass lenses helped man get a step closer to creating the modern camera.

3. The parts of the first modern camera were a glass lens, a dark box, and film.

4. Modern digital cameras and Niepce's camera both had light pass through a lens, into the camera, and expose the film. 

5. To capture an image, digital cameras use an electronic sensor called a CCD. 

6. On Auto mode the camera will completely control the flash and exposure. On Program mode, you can control the flash.

7. The Portrait mode is used to blur out the background. It works by using the fastest aperture.

8. The Sports mode is used to freeze motion. It works by using the highest shutter speed possible. 

9. You should do a half press on the trigger button to have more control over focus and to have a faster camera response time.

10. This symbol means disabled flash. You would use this when you want to use natural light. 

11. This symbol means auto-flash. When this is in use, if the camera thinks it needs more light, the flash will automatically go off. 

12. If there is too much light in your photo, it will be washed out.

13. If there is not enough light in your photo, it will be too dark.

14. A "stop" changes the brightness of the light. 

15. If there were 2 suns, the new planet would be 1 stop brighter.

16. If there were 4 suns, the new planet would be 2 stops brighter.

17. A longer shutter speed allows more light.

18. A shorter shutter speed allows less light.

19. The aperture controls the amount of light that comes in.

20. You can increase the amount of light in the aperture by using a smaller F-stop.
