3. In 1827 Joseph Nicéphore Niépce added the final touch. He added film to create the first successful photograph, and the only parts were a glass lens, a dark box, and film.
4. The the latest digital cameras work the same way as their ancestors. Light passes through the lens, into the camera, and exposes the film.
5. Replacing old-fashioned plastic film, digital cameras capture the images with an electronic sensor called a CCD. Photographs are stored on reusable computer memory devices.
6. In auto mode the camera will completely control flash and exposure. In program mode automatic-assist, just point and shoot.
7. Portrait mode is use to attempt to blur out the background, the camera will try to use the fastest available lens setting (aperture).
8. Spot mode is use to freeze motion, the camera will use the highest shutter speed possible.
9. You should do a half press on the trigger button because you get faster camera response time, more control over focus, and encourages better composition.
10. This symbol means no flash. There are many cases where you may not want flash at all. The mood of the photograph can sometimes be more dramatic when the natural light is used.
11. This symbol means auto flash In most camera modes, Auto-flash is enabled by default and will automatically fire if the camera thinks it needs more light.
12. Too much light and the picture will be washed out.
13. Not enough light and the picture will be too dark.
14. The term "stop" is used in every aspect of photography to represent a relative change in the brightness of light.
15. One stops brighter is the new planet if there are two sons instead of one.
16. Two stops brighter is the new planet if there are four sons instead of two.
17. Longer shutter speeds = more light
18. Shorter shutter speeds = less light
19. The aperture on a camera controls light.
20. To increase the amount of light you move f-stops.
