The Three Pillars of Exposure: Aperture, ISO, Shutter Speed

 F2.8
 F16



1. What part of the body should we closely relate aperture?
 our eyes.
2. Finish this sentence - the smaller the Aperture less light enters the retina, the higher the Aperture  more light enters the retina.
3. In your own words tell me how aperture impacts Depth of Field?
 the part of image that is sharp and blurry.

high
 at Blue and Gold night, i would use high shutter speed to take pictures.

At the beginning while the sun is still partially up and the courtyard has reasonable light

  • a.) the dunking booth
  •  fast
  • b.) the food eating contest
  •  fast
  • c.) the rock climbing wall
  •  slow
  • d.) someone working at a booth
  •  slow
  • e.) the DJ/MC working at the middle of the circle
  •  slow
  • f.) the Diamonds performance.
  • fast
Towards the end when there is no sun and it is dark so there is not enough light to see from one end of the courtyard to the other.

  • a.) the dunking booth
  •  slow
  • b.) the food eating contest
  •  slow
  • c.) the rock climbing wall
  •  medium
  • d.) someone working at a booth
  •  slow
  • e.) the DJ/MC working at the middle of the circle
  •  medium
  • f.) the Diamonds performance.
  •  medium
2. List the THREE settings your camera has regarding setting shutter speed (these are found at #5 on the Shutter Speed website. Explain how each works - DO NOT COPY AND PASTE, use your own words

Aperture Priority: auto set aperture speed

Shutter Priority: auto set shutter speed

Manual: set both aperture and shutter manually

ISO200

ISO6400





  • F4 
  • ---1/112 sec
  • F5.6 
  • ---1/60 sec
  • F8
  • ---1/60 sec
  • F11
  • ---1/60 sec
  • F16 
  • --- 1/30 sec
  • F22
  • ---1/15 sec


Now its your turn at each F-stop tell me what the background looks like. Is it in focus or blurry? 
blurry
Finally, what is happening to the subject (the people) at SLOW Shutter Speeds? What could the photographer do to help combat this problem?
slow motion
What is the lowest Shutter Speed do you think a photographer can hand-hold the camera without a tripod?
 100
