Aperture
• As well as letting in
light, the aperture
setting also
changes the depth
of field resulting in
more background
blurriness.
• Aperture 20 stops
a lot of light, and it
makes more of the
subject in focus,
and less blurring
• Aperture 3 lets in
alot of light, and
also creates a lot of
blurring
• The same photo
with different
aperture settings
changes the
blurriness for a
different effect
