The Camera

1. The effect came to be known as the camera obscura which is Latin for dark room. This was the first camera. The hole acted like a lens, focusing and projecting light onto the wall of the dark chamber.
2. Issac 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.
4. New cameras are very easy to use, just point and shoot. The camera's built-in computer handles focus and exposure so you don't have to.
5. Light passes through the lens, into the camera, and exposes the film. And guess what? The end result is still a photograph.
6. Operating modes are the most basic, and essentially tell the camera whether to take pictures or display them. Some cameras only have on and off. Operating modes can usually be found on buttons or dials on the camera body.
7. To attempt to blur out the background, camera will try to use the fastest available lens setting (aperture).
8. To freeze motion, camera will use the highest shutter speed possible.
9. If the subject is somewhat off-centre, the auto-focus may be fooled. You have probably seen this effect many times before. A half-press will tell the camera that you're almost ready to take a shot and to be prepared, triggering the following things to happen
10. Auto-Flash, In most camera modes, Auto-flash is enabled by default and will automatically fire if the camera thinks it needs more light.
11. 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.
12. Too much light and the picture will be washed out. Not enough light and the picture will be too dark. A good photograph depends on calculating the exposure settings that will give the film the "right" amount of exposure.
13. It will be dark.
14. The term "stop" is used in every aspect of photography to represent a relative change in the brightness of light.
15. 1

17. It has more light.
18. It has less light.
19. Before light reaches film, it must pass through an opening called an Aperture. The aperture is like a pupil. You can control the aperture by setting the "Aperture Opening", also known as an F-Stop.
20. The longer exposures  like 1 second  give much more light to the film than a 1/1000 of a second exposure. So even though the number may look bigger, don't be deceived!
