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


F2.8 


F16

1. It is easier to understand the concept if you just think about our eyes. 

2. The smaller the Aperture the larger the f-number, the higher the Aperture the smaller the f-number.
3. The better and more focus it is depth of field seems to have a more clearer photo.


 High Shutter Speed

Slow Shutter 

Shutter Speed - the time for which a shutter is open at a given setting.

                      Reasonable Light 
a.) the dunking booth - Fast
b.) the food eating contest - Medium
c.) the rock climbing wall - Slow
d.) someone working at a booth - Medium
e.) the DJ/MC working at the middle of the circle - Medium
f.) the Diamonds performance - Fast 

Dark
a.) the dunking booth - Medium
b.) the food eating contest - Fast

 f.) the Diamonds performance - Medium

"Auto Mode" is when it automatically shoots in both shutter sound & aperture.
"Shutter Priority" sets the camera to shutter speed & the camera automatically chooses the aperture itself.
"Manual" sets the camera in both shutter speed & aperture manually.

ISO 




1. What are the advantages of shooting with a higher ISO setting at a sporting event like a night football game?
It catches the action shots. 
2. What suggestions did the author make about using a low ISO?
Less sensitive
3. What suggestions did the author make about using a high ISO?
 More sensitive. 

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

The background gets darker, and unfocused.
