2. “The total amount of light allowed to fall on
the photographic medium during the process
of taking a photograph”
More light = Brighter that area
Color
Sun vs Moon over beach
3. Controlling exposure
We control how much
light is let in
ISO
Shutter
Aperture
4. Brightness is measured
in Exposure Value “EV”
or f-stops
Step up – doubling
Step down- halving
What you see may not be
what you get

6. Put camera on Back in MANUAL
MANUAL mode mode
Find controls to adjust Same scenes as
the 3 exposure points before, adjust up and
Set camera to AUTO down a few f-stops and
note the difference
find various lighting
situations and look Purposely over or
through viewfinder and under expose for artistic
hold down the shutter experiment
half way to see what
the camera has set
7. “an opening” f ratio sequence in
Can be adjusted (open stops
or close) to control light 1
let in 1.4

9. Depth of Field
Region of photo that
is in focus
Larger the Aperture
(small f/#)
Smaller the Aperture
(large f/#)
12. Find interesting Find a small object
things that are at against a background
many distances from Adjust aperture to
you. isolate the subject
Photography with from everything else
different apertures Find a house or
and keeping photo landscape and adjust
with correct exposure accordingly to have
the whole photo in
focus
13. Fast
Freeze motion in time
Slow
Show motion
Longer shutter
Ex. Make moving
water look fluffy
Long exposure at
night
Can capture image in
dim lighting
14. Shutter- Fast or Slow?
Aperture- Big opening or little?
Point of view? (worms eye, normal, birds eye)
Composition (principle/elements of art)
Rule of Thirds?
What does the photo say to you? How does it
make you feel?
