Camera

The Camera

1. They have the old camera in a dark room and they put a tiny hole in the wall. Light focuses through the hole and a projection of the picture is shown upside down on the wall.
2. Isaac and Christian perfected the understanding of optics and the process of glass lenses.
3. The first modern camera had a glass lens, a dark box and a film.
4. Modern digital cameras and Niepce's camera both work when the light passes through the lens, into the camera and exposes the film which creates a photograph.
5.  We have replaced a plastic film with an electronic censor called a CCD that stores all of the pictures in the memory.

Camera Modes

6. The difference between auto mode and program mode is that auto mode does everything by itself while program mode lets you control a couple of the settings.

7. Portrait mode is used to attempt to blur our the background by using the fastest lens setting available. 

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

9. In manual mode you have to set the shutter and aperture.

The Half Press

10. If you do a half press on the trigger button, it tells the camera you're almost ready to take a shot so the camera can prepare by focusing and there's no delay in the picture taking.

Controlling Flash

11. This symbol shows that the flash is disabled or that there's no flash. You can use this when you want to take a dramatic picture and the flash won't give that effect.

12. This symbol shows that auto flash is enabled. You would use this when it is set by default in your camera.

Introduction to Exposure

13. If there is too much light in the picture, the picture will be washed out.

14. If there is not enough light in the picture, your picture will be too dark.

The Universal Stop

15. A stop is a relative measurement of light.

16. The world would be 1 stop brighter if there was two suns.

17. If there was 4 suns, the world would be 2 stops brighter.

Shutters and Aperture

18. Longer shutter speed lets there be more light.

19. Shorter shutter speeds let there be less light.

20. The aperture controls the amount of light coming through to the film.

21. The bigger the opening, the more light comes through.
