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



APERTURE


 

F2.8 would be the first one that has the lens more open and F16 would be second to the last one with the lens more closed. These are known as "f stops" which this helps describe the size of the aperture. 


- What part of the body should we closely relate aperture? 
Our pupils
- The smaller the Aperture the larger f number, the higher the Aperture the smaller f number 
- The aperture impacts depth of field



SHUTTER SPEED 

high shutter speed 

slow shutter speed 

At the beginning while the sun is partially up
  • a.) the dunking booth: Fast
  • b.) the food eating contest: Slow
  • c.) the rock climbing wall: Medium
  • d.) someone working at a booth: Fast
  • e.) the DJ/MC working at the middle of the circle: Slow
  • f.) the Diamonds performance: Slow  

 At the end where there is no sun 

  • a.) the dunking booth: Slow
  • b.) the food eating contest: Slow
  • c.) the rock climbing wall: Medium
  • d.) someone working at a boot: Medium
  • e.) the DJ/MC working at the middle of the circle: Fast
  • f.) the Diamonds performance: Fast  
 Shutter Priority is when you put it on shutter speed then after that the camera will automatically select the aperture

ISO  


ISO 200 & 3200 

- the advantages of shooting with a higher ISO setting at a sporting event like a football game would be you would be able to capture all of the action faster. 
- The author suggested that using a low ISO is when you have plenty of light 
- The author suggested that using a high ISO is when you when there isn't enough light. 

  • F4 - not really visible
  • F5.6 - kind of visible
  • F8 - more visible
  • F11 - looks the same like the last one
  • F16 - visible
  • F22 - very visible
