Aperture and Shutter Speed Practice

• F2.8 – looks the best at 1/250th of a second shutter speed.
• F4  – looks the best at 1/125th of a second shutter speed.
• F5.6 – looks the best at 1/60th of a second shutter speed.
• F8  – looks the best at 1/30th of a second shutter speed.
• F11  – looks the best at 1/30th of a second shutter speed.
• F16  – looks the best at 1/15th of a second shutter speed.
• F22  – looks the best at 1/15th of a second shutter speed

• At F2.8 there is no background visible. It is very blurry and all you can really see is the couple.
•  F4 how much background is very blurry.
• At F5.6how much background is a little clearer but still blurry.
• At F8 how much background is clearer, you can see the shapes of the windows. 
• At F11 how much background is a only a little out of focus.
• At F16 how much background is only a little out of focus, more of the details are visible. 
• At F22 how much background is as in focus as the couple is.  

1. Consider what is happening to the people themselves at slow Shutter Speeds.

The people are clearer; more in focus.

2. In a real shooting situation, what should the photographer do to lessen this problem?
Have the couple hold still while taking the photo.

3. What combination of aperture and shutter speed do you think produces the best portrait? Why?

Shutter at 1/500th of a second and aperture at f/2.8. The couple is in focus with a good about of lighting the background is blurred out.
