Aperture, Shutter Speed, ISO - How do they all work?

1. What part of the body should we closely relate aperture? Pupil
2. Finish this sentence - the smaller the Aperture _The larger the f-number_, the higher the Aperture _The smaller the F-number_.
3. In your own words tell me how aperture impacts Depth of Field? It determines if the background will be focus or not.

Slow shutter speed
 High shutter speed


At the beginning while the sun is still partially up and the courtyard has reasonable light
a.) the dunking booth High shutter speed
b.) the food eating contest High shutter speed
c.) the rock climbing wall Slow shutter speed
d.) someone working at a booth Slow shutter speed
e.) the DJ/MC working at the middle of the circle High shutter speed
f.) the Diamonds performance. High shutter speed

Towards the end when there is no sun and has gotten dark enough that you can't see from one end of the courtyard to the other.
a.) the dunking booth Slow shutter speed
b.) the food eating contest Slow shutter speed
c.) the rock climbing wall Slow shutter speed
d.) someone working at a booth Slow shutter speed
e.) the DJ/MC working at the middle of the circle Slow shutter speed
f.) the Diamonds performance. Slow shutter speed


1. What are the advantages of shoot at a higher ISO at a sporting event like basketball or a night football game? The picture will be more sensitive and better lighting.
2. What suggestions did the author make about using a low ISO? if there is plenty of light use a low iso
3. What suggestions did the author make about using a high ISO? You should increase iso when there is no light and when you are indoors and don't use a flash increase the iso.

F4 - 1/125 sec background is still blurry.
F5.6 - 1/60 sec you can start noticing the background but not that much.
F8 -  1/60 sec the background got a little more clear.
F11 - 1/30 sec the background is clear and you can notice some detail
F16 - 1/30 sec you can notice more detail in the background
F22. - 1/15 sec the background is sharp and with detail

What is the lowest Shutter Speed do you think a photographer can hand-hold the camera? ISO 100 ?
