The Camera

1. The Camera Obscura effect is achieved by creating a small hole in the wall and then projecting light through the hole. By doing this, the hole acts as a lens. The effect became known as the first camera.

2. 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. A glass lens, a dark box, and film were the materials used to make the first modern camera.

4. Light passes through the lens, into the camera, and exposes the film, making a photograph.

5. An electronic censor called a CCD.

6. In auto mode, the camera completely controls things like flash and exposure. In program mode, you are able to choose flash and exposure.

7. Portrait is used as an attempt to blur out the background, and occurs when the camera uses the fastest available lens setting (aperture).

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

9. The photographer must set both the shutter and aperture mode.

10. You should use The Half Press camera button to have faster camera response time, more control over focus, and better composition.

11. This symbol means no flash. You would use the mode when you didn't want flash in your photo.

12. This symbol shows auto flash. You would use auto flash to be able to automatically fire if the camera thinks the photo needs more light.

13. Too much light will cause the photo to be washed out.

14. Not enough light and the picture will be too dark.

15. A "stop" is a relative measure of light.

16. 1 stop

17. 2 stops

18. Longer shutter speeds cause more light.

19. Shorter shutter speeds cause less light.

20. The aperture controls the brightness.

21. You increase the amount of light by creating a larger opening.
