1. Shutter speed controls the duration of the exposure
2. ISO speed controls the sensitivity of your camera’s sensor to a given amount of light
3. Underexposed means you collect to little
4. Overexposed means you collect too much
5. A photographer’s exposure determines how light or dark an image will appear when it’s been captured by your camera
6. A cameras shutter determines when the camera sensor will be open or closed to incoming light from the camera lens.
7. Faster shutter speed means a shorter exposure time.
8. Photographer slang “stopping down” or “opening up” means increasing or decreasing the f-stop Aperture controls the area over which light can enter your camera.
9. Value, respectively.
10. Every time the f-stop value halves, the light-collecting area quadruples.
11. ISO speed determines how sensitive the camera is to light.
12. Aperture affects depth of field.
13. Shutter speed affects motion blur
14. ISO speed affects image noise
15. Shutter speed is a powerful tool for freezing or exaggerating the appearance of motion
16. Freezing movement shot can be taken hand-held without camera shake
17. Most photographers memorize the f-stop numbers that correspond to each doubling/halving of light
18. Above f-stop numbers are all standard options in any camera.
19. The range of values may also vary from camera to camera (or lens to lens)
20. A narrow aperture range usually isn’t a big problem
21. A greater range does provide for more creativity flexibility
22. There is wide aperture
23. There also is narrow aperture
24. Faster shutter speed is usually achieved by increasing the ISO
25. Camera permits shutter speeds which are longer than ordinarily allowed for hand-held shots
