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

APERTURE

1. The body part that we relate aperture to is the eye because we use them to focus on the things.
2.The smaller the Aperture, the larger the F-number. The higher the aperture, the smaller the F-number.
3. Aperture affects the depth of field because the size of the aperture has an impact on the area of the image that is sharp.

SHUTTER SPEED

1. I would use different shutter speeds for different events. 
Sun is still out:
a) For a booth in the middle of the yard by the tree I would use a a low shutter speed because there isn't a lot of motion going on.
b) for a food both I would also use low shutter speed.
c) I would use a high shutter speed to capture the Silver Star's performance because they're dancing and it would be easier to capture their movement.
d) I would also use a high shutter speed to shoot photos of the students dancing in the courtyard because there is a lot of motion going on.
e) Even though there is a lot of movement going on when the people are streaming in throughout the front doors, I would use a low shutter speed because it would look really cool if the picture was blurry.
f) I would use a high shutter speed to capture the students shooting basketballs to capture their movement. 
Darker outside: 
a) For a booth in the middle of the yard by the tree I would use a low shutter speed.
b) For a food booth outside under the tree I would use a high shutter speed.
c) For the Silver Star's performance inside the gym I would use a high shutter speed.
d) For students dancing outside I would use a low shutter speed.
e) For people streaming in from the front doors I would use a low shutter speed.
f) For the basketball booth where students are shooting hoops I would use a low shutter speed.

2. The 3 settings a camera has regarding shutter speed are...
1- Shutter priority- camera automatically selects the aperture
2- Manual- you can set shutter and aperture yourself
3- Aperture priority- camera calculates shutter speed

1. The advantages of shoot at a higher ISO at a sporting event like basketball or night football is you will be able to quickly capture an image. Also, you'll be able to get ultra-fast shots.
2. The author suggested to use the lowest  ISO when when there is plenty of light. The lowest ISO is usually ISO 100 or 200. By doing this you'll be able to retain the most detail and have a high quality photo.
3. The author suggested to use a high ISO when there isn't enough light. He also suggests using the setting "Auto ISO" and set it to the maximum, which is ISO 800. By doing this you'll be able to freeze motion.
