1. The Mechanics Behind the Lens

2. The Exposure Triangle
Aperture
Shutter Speed
ISO sensitivity

3. ISO
Aperture
Shutter Speed
ISO sensitivity

4. Aperture & Shutter Speed
Work together during
a capture to control
the amount of light
entering the camera
to obtain a properly
exposed picture

5. at f/5.6
Shutter Speed 1/500 1/250 1/125 1/60 1/30
F/stop f/2.8 f/4 f/5.6 f/8 f/11
at 1/125 sec.

6. Aperture
Mechanical opening
that regulates how
much light enters
the camera through
the lens.

7. Aperture
The physical opening
of the camera lens
Called F-Stop
Higher the “F” number
the smaller the
opening
F/22 small
F/1.2 big

8. Aperture
Controls Depth of
Field(DOF)
F/18 DOF how much is in
focus front to back.
F/22 large DOF
F/1.2 very small DOF
F/5.6

9. Aperture
Shallow DOF
Allows you to isolate
a subject from a
distracting
background taking
the subject out of
context

10. Aperture
Long DOF
Allows you to show
the background or
foreground to place
your subject into
context of what is in
the surrounding
area

11. Shutter Speed
The time duration that
the sensor can
record light
Measured in seconds
1/1000 fast
1/25 slow
2 very slow

12. Shutter Speed
Controls motion
Fast = Freeze
Slow = Blur
Speeds slower than
1/30 are subject to
camera shake.

13. Shutter Speed
Control camera shake
by:
Holding properly
Bracing
Using a support
Finding more light to
allow a faster shutter
speed

14. Aperture and Shutter Speed
Are inversely
proportional
Each have trade
offs

15. Aperture and Shutter Speed
Low f/stop means
more light and a
faster shutter but
less DOF
Slow shutter means
more light and
higher f/stop but
can cause motion
to blur

16. Aperture
&
Shutter Speed
Automatic Setting
Camera Adjusts to
Best Exposure
Can Be Modified for
Specific Situations
Sport
Night
Portrait
Manual Adjustment

17. ISO
Increases the sensitivity
of the sensor.
Faster shutter speeds
Smaller apertures
Trade off - NOISE

19. Picture Quality & File Size

20. Quality
Image Quality
refers to how
much
compression is
applied to the
photo to save on
storage space.
Use HIGHEST
Low Quality Best Quality QUALITY
** Not all cameras
have this setting

21. Image Size
Refers to how many
pixels wide by high
the actual capture.
3872x2592 (FINE)*
2896x1944 (NORM)*
1936x1296 (BASIC)*
Turns down the
megapixels
*Nikon D80 10.2mpx camera

22. Quality x Size = File Size
Assume a 2gb card
at highest quality
File size Qty stored
4.8 mb ~ 266 fine
2.7 mb ~ 466 norm
1.2 mb ~ 503 basic

23. Shoot in
Fine or Normal
Format
Your photo could end
up on a poster, or
the web, or a large
format banner
Don't choose
RAW format

28. Cool Pix Tips
Avoid using the flash.
Use the self timer's 2
second delay to help
prevent camera shake
in low light.
Keep an extra set of
batteries on hand
(2 AA)
