The Camera

The Camera:
1.) Inside a completely dark room, a tiny hole is made in one wall. Through the hole light is focused, and the outside scene is projected (Upside Down) on the opposite wall. It is achieved by making a small hole in one wall, and allowing light to pass through it.

2.) High quality glass lenses.

3.) A glass lens, film, and a dark box.

4.) A lens, dark box, and film.

5.) An electronic sensor called a CCD.

Camera Modes:
6.) The difference between Auto Mode & Program Mode is on Auto mode you cannot control flash and exposure, and with Program Mode you can control flash and a few other settings.

7.) Portrait Mode is used to attempt to blur out the background. How It Works: The camera will try to use the fastest available lens setting (Aperture.)

8.) Sports Mode is used to freeze motion. How It Works: The camera will use the highest shutter speed possible.

The Half Press:
9.) You should use the Half press if what your trying to take a picture of is off-centre, and your trying to get the camera focused.

Controlling Flash:
10.) Disabled Flash: There is no flash.

11.) Auto-Flash: Will automatically fire if the camera thinks it needs more light.

Introduction To Exposure:
12.) If there is too much light then the picture will be washed out.

13.) If there is not enough light then the picture will be too dark.

The Universal Stop:
14.) A "Stop" is a relative change in the brightness of light.

15.) The planet is 1 "Stop" brighter.

16.) The planet is 1 "Stop" brighter.

Shutters and Aperture:
17.) A longer shutter speed gives you more light to the film.

18.) A shorter shutter speed gives less light to the film.

19.) The aperture controls the amount of light that enters the camera.

20.) To increase the amount of light you should use Smaller F-stops numbers.
