Shutter speed, Aperture, and ISO.

 Aperture.

1. What part of the body should we closely relate aperture?
The eyes because your pupils control the amount of light by changing size just as apertures do.

2. Finish the sentence. 
The smaller the Aperture lower the number, the higher the Aperture higher the number.


3. In your own words tell me how aperture impacts Depth of Field?
A smaller aperture keeps the foreground and background in focus. A larger aperture blurs the background creating a larger depth of field. 





















F18 Aperture.
















F2.8 Aperture.




Shutter speed. 

At the beginning while the sun was still up and the courtyard had reasonable good light

a.) a booth in the middle of the yard near the Tree

Fast
d.) students dancing near the center of the courtyard
Fast
e.) people streaming in from the front doors
Fast
f.) the basketball booth where students are shooting basketballs at a hoop
Slow
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.) a booth in the middle of the yard near the Tree
Medium
b.) a food booth outside under one of the big red awnings
Very slow
c.) the Stars performance inside the gym
slow
d.) students dancing near the center of the courtyard
slow
e.) people streaming in from the front doors
medium
f.) the basketball booth where students are shooting basketballs at a hoop
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 mode, The camera selects the shutter speed based on aperture. 

Shutter Priority mode, the camera selects aperture based on speed.

Manual Mode, everything is controlled by YOU.

ISO

1. What are the advantages of shoot at a higher ISO at a sporting event like basketball or a night football game?
The camera needs less light to shoot high speed.

2. What suggestions did the author make about using a low ISO?
Outdoor and low motion stuff. 
3. What suggestions did the author make about using a high ISO?
When there isn't enough light to for the camera to go fast.
