camera history

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.In 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.

5Light passes through the lens, into the camera, and exposes the film. And guess what? The end result is still a photograph.

6The camera will completely control flash and exposure. On most cameras this is labelled "auto", on others simply "A". Some cameras only have program.

 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).

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

9Point 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

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.

13Most of the time, the inside of the camera is totally dark. When a photograph is taken, the camera opens and light from outside floods in through the lens. Light is projected onto film to make the exposure.

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

15You are an astronaught travelling to a new planet. To your dismay, when you arrive your discover that your light meter has broken during the journey. The new planet is identical to Earth, except that it has TWO suns instead of one.

16Aperture, shutter, and film settings are all divided up into "stops", even though the numbering systems are different.
