1. The camera obscura it was the first camera the hole acted like a lens, focusing and projecting light onto the wall of the dark chamber.
2. When isaac newton and christian Huygens perfected the understanding of optics and the process of making quality glass lenses.
3. For the first modern camera Niepce invented a glass lens, a dark box, and film.
4. modern digital cameras have in common with the one that Niepce invented is that the light passes through the lens, into the camera, and exposes the film.
5.The digital cameras capture the images with an electronic sensor called a CCD.
6. the difference between the auto mode and the program mode is that program automatic-assist, just point and shoot unlike full auto mode, you can usually control flash and a few other camera settings.
7. The portrait is use to attempt to blur out the background, the camera will try to use the fastest available lens setting(aperture).
8. The Sports mode is use to freeze motion , camera will use the highest shutter speed possible.
9. You should do a half press on the trigger button because the faster camera response time, more control over focus and encourages better composition.
10.

this is the auto flash you would use this if the camera thinks it needs more light.
11.

this is the disabled flash you would use it when you don't need the flash when you think the picture is good without the flash.
12. If you have too much light then the picture will be washed out.
13. If you don't have enough light then the picture will be too dark.
14. A "stop" is used in every aspect of photography to represent a relative change int the brightness of light.
15. There would be 1 stop brighter if the new planet had two sons instead of one.
16. There would be 2 stops brighter if the new planet had four sons instead of two.
17. The affect of a longer shutter speed would have more light.
18. The affect of a shorter shutter speed would have less light.
19. The aperture control is like a pupil you can control the aperture by setting the "Aperture Opening", also know as a F-stop.
20. Smaller F-stop numbers means larger openings and the larger openings mean more light, so you can increase the light by the longer exposures.
