Aperture, Shutter Speed and ISO - What are they?

Aperture questions:
1. We should closely relate the pupil to aperture.
2. The smaller the aperture size, the bigger the opening. The higher the aperture size, the smaller the opening.
3. The larger the aperture size is, the thinner the depth of field. The smaller the aperture size is, the larger the depth of field.

Shutter Speed questions:

High Shutter Speed

Slow Shutter Speed

Quick shutter speed is darker, longer shutter speed is brighter.

At the beginning when the sun was up and the courtyard still had reasonable light:

a. High shutter speed. the lighting outside is relatively decent.

b. A bit of a slower shutter speed so that the food booth under the awning isn't too dark, but still relatively high. Medium high or just medium.

c. Slow shutter speed so it's not too dark, since the performance is inside.

d. High shutter speed. Captures a lot of the detail and stops the students in time, and the lighting in the courtyard is decent enough that the image is not too dark.

e. The back lighting from the outside makes it bright enough that you may do high shutter speed to catch the small details of all of the people coming in. Might be good if they have positive expressions.

f. A high shutter speed to catch all of the details of a person shooting the hoop, since it is still bright enough outside to allow for it.

Near the end when there is no sun and it is dark enough that you can't see from one side of the courtyard to the other:

a. Low shutter speed. The lighting outside is very bad, and if you use a high shutter speed, it will be very hard to see.

b. Low shutter speed. The awning is bad enough on its own, but since the food booth is outside, it will be very dark.

c. A slow shutter speed is still needed, since the inside will not be affected by the outside lighting, and you do not want the students to be too dark.

d. Low shutter speed. It will capture the students while in motion, while still making them bright enough to be recognizable.

e. The darkness from outside will make a slow shutter speed preferable. This will also create the illusion of motion within the image.

f. A low shutter speed in order to have the person still be recognizable in the dark. Will capture the motions taken to shoot the hoop.

ISO questions:

ISO 200

ISO 6400

1. A higher ISO will make the players more visible and easy to see, since an inside basketball game or an outside night football game will be darker and more difficult to see.

2. Low ISO should be used as much as possible. To accommodate for the darkness, use a longer shutter speed as needed.

3. Sometimes, though, a higher ISO is needed because a longer shutter speed means motion blur. Increase a high ISO if you can't get a sharp and focused photo any other way. It is a last resort.
