Aperture and Shutter Speed Practice
F2.8 is best with 1/250 shutter speed
F4 is best with 1/125 shutter speed
F5.6 is best with 1/60 shutter speed
F8 is best with 1/60 shutter speed
F11 is best with 1/30 shutter speed
F16 is best with 1/15 shutter speed
F22 is best with 1/8 shutter speed
The background becomes more and more visible with each change in aperture.
F2.8 background isn't visible at all.
F4 background can only be made out slightly.
F5.6 background is slightly more visible, and you can make out the outlines of windows in the back. It is still blurry, however.
F8 is more visible, but still blurry.
F11 is more in focus. You can make out the entire building in the background.
F16 is more in focus. The couple is slightly blurred, and you can make out larger objects in the background.
F22 is the most in focus. The couple is slightly blurred, while you can now make out smaller objects in the background.
1. At slow shutter speeds, the movement of the people and the photographers are shown in the photo with the blurs.
2. A photographer would use a tripod or other tools to keep this problem in check.
3. I personally think that F5.6 with 1/60 shutter speed is the best. You can make out the background a little bit, but it keeps the subjects in focus.
