Camera History

The Camera
1. The "Camera Obscura" effect is achieved by 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.
3. The parts of the first modern camera invented by Niepce were a glass lens, a dark box, and film.
4. Modern digital camera and Niepce's camera in common because the are both still made out of a glass lens, a dark box, and film.
5. Digital cameras capture the images with an electronic sensor called CCD. Photographs are stored on reusable computer memory devices.
Camera Modes
6. The difference between Auto mode and Program mode is that, Auto mode will completely control flash and exposure. Program mode can usually control flash and few other camera settings.
7. Portrait mode is used for to attempt to blur out the background, the camera will try to use the fastest available lens setting (aperture).
8. The Sports mode is used to freeze motion, camera will use the highest shutter speed possible.
The Half Press
9. A half-press will tell the camera you're almost ready to take a shot and be prepared, trigging the focus look and getting a faster full-press respond.
Controlling Flash
10. The symbol means no flash. (Disable Flash)
11. The symbol Auto-Flash means that when you capture a photo, the camera automatically adjust its self of the amount of light that is needed.
Introduction to Exposure
12. If there is too much light, the picture will come out washed out.
13. If there isn't enough light the picture can come out to dark.
The Universal Stop
14. The term "stop", represents a relative change in the brightness of light.
15. The stops brighter is 1 to the new planet if there is two suns.
16. The stops brighter is 2 to the new planet if there are four suns.
Shutter and Aperture
17. The longer shutter speed (like 1 second) give much more light to the film than 1/1000 of a second exposure.
18.  The effect of the shorter speed is less light.
19. The aperture controls light reaching the film.
20. To increase the amount of light for aperture, it does so by closing up to restrict light , and opening up to let it through.
