Aperture, Shutter Speed, ISO- What Are They?

Aperture

F 2.8

F 16

1. We should closely relate photography to the human eye. The aperture would be like the pupil of an eye because size of the pupil determines the amount of light can enter the retina, similar to how the camera sensor works. A large pupil is equivalent to a large aperture and a small pupil is equivalent to a small aperture.

2. The smaller the aperture the smaller the pupil, the larger the aperture the larger the pupil. 

3. The aperture impacts the depth of field by controlling the area in focus. The larger the aperture the smaller the area in focus. The smaller the aperture the larger the area in focus.

Shutter Speed

Slow Shutter Speed

Fast Shutter Speed

Day Time:

a.) a booth in the middle of the yard near the Tree- low shutter speed

b.) a food booth outside under one of the big red awnings-low shutter speed

c.) the Stars performance inside the gym- high shutter speed

d.) students dancing near the center of the courtyard- high shutter speed

e.) people streaming in from the front doors- low shutter speed

f.) the basketball booth where students are shooting basketballs at a hoop- high shutter speed

Nighttime: 

a.) a booth in the middle of the yard near the Tree- low shutter speed

b.) a food booth outside under one of the big red awnings- low shutter speed

c.) the Stars performance inside the gym- high shutter speed

d.) students dancing near the center of the courtyard- low shutter speed

e.) people streaming in from the front doors- low shutter speed

f.) the basketball booth where students are shooting basketballs at a hoop- high shutter speed

Aperture Priority Mode: This is when the photographer has to set the lens aperture and the camera will set the shutter speed automatically.

Shutter Priority Mode: This is when the photographer has to set the shutter speed and the camera will set the aperture automatically.

Manual Priority Mode: This is when the photographer has to set the aperture and shutter speed by themselves, by hand.

ISO

1.Shooting at a higher ISO during sporting events allow the subject to be captured in time, frozen, instead of blurry.

2. Try to sick with the lowest ISO possible, but definitely use it whenever there is a lot of light and certain dim environments.

3. If there isn't enough time for the camera to take a picture quickly, then increase the ISO.
