The Camera

1.  Inside a completely dark room, a tiny hole is created in one wall. Through the hole, light is focused and the outside scene is projected upside down on the opposite wall. The hole acts as a lens, focusing and projecting light on to the wall of the dark room.

2. In the 17th century, the Issac Newton and Christian Huygens invented high quality glass lenses.

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

4. Light passes through the lens, into the camera, and exposes the film. The end result is a photograph.

5. With an electronic sensor called a CCD.

6. The camera will completely control flash and exposure. On most cameras this is labelled "auto", on others simply "A". Some cameras only have program. automatic-assist, just point and shoot. Unlike full auto mode, you can usually control flash and a few other camera settings.

7. To attempt to blur out the background, camera will try to use the fastest available lens setting (aperture).

8. To freeze motion, the camera will use the highest shutter speed possible.

9.  It is faster camera response time, more control over focus and encourages better composition

10. Disabled Flash: No flash. There are many cases where you may not want flash at all. The mood of the photograph can sometimes be more dramatic when the natural light is used.

11. Auto-Flash: In most camera modes, Auto-flash is enabled by default and will automatically fire if the camera thinks it needs more light.

12. If there is too much light the picture will be washed out. 

13. If there is mot enough light the picture will be too dark.

14. The term "stop" is used in every aspect of photography to represent relative change in the brightness of light.

15. One

16. Two

17. The longer exposures give much more light to the film than a 1/1000 of a second exposure.

18. The shorter exposures give much less light to the film than a 1 second exposure.

19. The aperture works like a pupil. 

20. You can control the aperture by setting the "Aperture Opening", also known as an F-Stop.
