Camera History

1. The "camera obscura" effect is:
It was achieved by being inside a completely dark room, a tiny hole is created in one wall. Through the hole light focused, and the outside scene is projected on the opposite wall.
2. When Isaac Newton and Christian Huygens perfected the understanding of optics and the process of making high quality glass lenses is when they came one step closer to creating the modern camera.
3. The parts of the first modern camera that Niepce invented were, a glass lens, a dark box, and  film.
4. Modern digital cameras and the camera Niepce created work the same way, light passes through the lens, into the camera, and exposes the film.
5. Digital cameras use an electronic sensor called a CCD to capture an image.
6. Auto Mode is when the camera will completely control flaw and exposure, while Program Mode is automatic-assist, meaning just point and shoot, and you can control flash and other settings.
7. Portrait is used to attempt to blur out the background, and the camera will try to use the fastest available lens setting.
8. The sports mode is used to freeze motion, meaning the camera will use the highest shutter speed possible.
9. You should do a half-press trigger so that the camera focuses on the scene.
10. This symbol means that there is no flash. You would use it when you want to use natural light
11. This symbol means that the Auto-flash is enabled. You would use it when there isn't enough light.
12. Too much light in the photo means the picture will be washed out.
13. If there is not much light the picture will be too dark.
14. A "stop" is a relative measurement of light.
15. The new planet is 1 stop brighter if it had two suns instead of one.
16. The new planet is 2 stops brighter if it had four suns instead of two.
17. Longer shutter speed means more light.
18. Shorter shutter speed means less light.
19. The aperture controls the openings.
20. You can increase the amount of light with making them larger openings by making smaller F-stops numbers.
