2. What is Aperture?
Aperture refers to the
amount of light passed
through a camera lens
Diaphragm opens and
closes in order to
achieve this
Works very much like
the pupil of a human
3. Side Effects of Aperture
Controls how fast or slow the shutter speed is
When the aperture changes so does the depth of field
The depth of field means how much the shot is in focus
Ex)
Large aperture opening Small aperture opening
4. Regulating the Aperture Opening
The aperture opening is
also known as an “F Stop”
A small F stop number= a
large opening and more
light
A large F stop number= a
small opening and less
light
Common F stop numbers
include: 1.4, 2.8, 4, 5.6, 8,
11 , 16, 22, and 32
5. Regulating Your Aperture
Aperture and shutter
speed are already set by
the camera
You can adjust the
settings by shifting the
control dial

This includes photos like family portraits, and
landscapes

7. Using Large Aperture
Most commonly used in motion pictures, when the
background image tends to not be as important
