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.

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
