Camera History

1Inside 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.
2In the 17th century, 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.-The parts of the firs camera was 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.-Auto mode do automatic the control flash and exposure; and Program mode is the most used by professionals because they can concentrate on getting the shot instead of exposure calculations.
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.-Point the camera at the subject and half-press. Wait for focus lock. While focusing, the camera will show a blinking focus indicator (usually a green dot). When you hear a beep and the indicator stops blinking, the camera is telling you it's ready to go.
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.-Too much light and the picture will be washed out.
13.-Not enough light and the picture will be too dark.
14.-The term "stop" is used in every aspect of photography to represent a relative change in the brightness of light.
15.-1 sun+ 1sun= 1 stop
16.-2 sun+ 2sun= 1 stop
17.-More light.
18.-Less light.
19.-Controls the light entering the camera.
20.-Opening the aperture
