The Camera

1. The camera obscure effect is when there is a completley dark room and a small hole is created in one wall, and light is focused through the hole and the object or scene outside is projected upside down on the opposite wall. It acted like a lens focusing and projecting light onto the wall go the dark room.
2. Isaac Newton and Christian Huygens perfected the idea of optics and the process of making high quality glass lenses.
3. He added film to the camera, so the camera had a glass lens, a dark box and film.
4. Light still passes through the lens and exposes the film and we get a photograph.
5. Digital cameras use and electronic sensor called a CCD, and pictures are saved on a memory device.
6. In auto mode everything automatically happens, like flash will go off and focus on its own. In program mode you can control the flash and exposure and focus in any way you want.
7. Portrait mode will be used to attempt to blur the background. the camera will use the fastest lens setting to do this.
8. Sports mode is used to capture things in motion and uses the highest shutter speed.
9. When you half press, you focus on whatever you're aiming at. When you are doing this it will focus and when you are ready you can take the shot.
10. This symbol means there will be no flash. You can use it to create a more dramatic look with natural lighting.
11. Auto flash is used when the camera thinks the photo needs more light.
12. Too much light will wash out the photo.
13. Not enough light will make the photo too dark.
14. A stop is the amount of light that there is.
15. One stop brighter.
16. Two stops brighter.
17. A longer shutter speed means more light in the photo.
18. A shorter shutter speed means less light in the photo.
19. The aperture controls how much light gets through.
20. You can control the aperture by setting the aperture opening.
