The Three Pillars of Photography

Aperture F2.8


Aperture F16


1. The pupil is the body part that people closely relate to aperture because the pupil dilates depending on the amount of light passing through it, similar to a camera lens.
2.  The smaller the aperture the more focused the background of an image is. The higher the aperture the more focused a central object in a photo with become.
3. Aperture affects Depth of Field (the area of the image that appears sharp) directly since a smaller aperture focuses all items in a photo while a higher aperture does the opposite.




Photo taken at high shutter speed


Photo taken at slow shutter speed

1. When there's plenty of light in the courtyard, the shutter speed I would use for a photo of:
a. a booth in the middle of the yard near the Tree, a slow shutter speed.
b. a food booth outside under one of the big red awnings, a high shutter speed
c. the Stars performance in the gyms, a slow shutter speed
d. Students dancing near the center of the courtyard, a slow shutter speed
e. People streaming in from the front doors, a slow shutter speed
f. the basketball booth where students are shooting basketballs at a hoop, slow shutter speed

When it's mostly dark in the courtyard, the shutter speed I would you for a photo of:
a. a booth in the middle of the yard near the Tree, a high shutter speed
b. a food booth outside under one of the big red awnings, a high shutter speed
c. the Stars performance in the gyms, a high shutter speed
d. Students dancing near the center of the courtyard, a high shutter speed
e. People streaming in from the front doors, a high shutter speed.
f. the basketball booth where students are shooting basketballs at a hoop, high shutter speed

2. The three settings a camera has regarding setting shutter speed are Aperture Priority, Shutter Priority and Manual mode. With Aperture Priority you set the aperture lens while the camera selects a shutter speed. Setting the camera to Shutter Priority, the camera sets an aperture lens while you select a shutter speed. In Manual mode you can set the shutter speed and aperture lens yourself.


ISO 200



ISO 3200

1. Setting the ISO to higher setting when the setting of a picture is dark would be an advantage in using a higher ISO while taking photos at a late night football game.
2. When there's high amounts of light, stick to a low ISO so you can achieve more detail.
3. Use a higher ISO if there's not enough light for the camera to quickly capture an image.
