This document defines key photography terminology: Shutter speed determines exposure time, ISO controls light sensitivity, and aperture sets depth of field. Automatic exposure lets the camera control settings, while manual exposes requires photographer input. Color balance adjusts hue intensity. Composition positions the subject. The rule of thirds guides subject and horizon placement. Complementary colors contrast, and analogous colors blend smoothly.

2. Shutter speed Is how
long the camera
shutter stays open
changing the amount
of exposure and light
the image will get.
Shutter Speed

3. The ISO number is the
sensitivity to light, the
lower the number the less
sensitive to light your
camera will be
ISO

4. The aperture is the Opening
on the camera lens that
Determines the amount of
light that goes into the
image. The Depth of field is
the amount of space that an
image is sharpest. A Large
depth of field will leave the
entire image sharp where as
if you would like to focus on
a certain part of the image a
lower depth of field would
be better.

5. Putting a Camera
on Automatic
exposure will Do
everything for you
determined on the
picture you are
trying to get
Automatic Exposure

6. Manual Exposure is the
photographer will have
to Choose all settings
themselves allowing
them to create their
desired image on their
own.
Manual Exposure

7. The colour balance is
choosing the intensity of
chosen colours for example
you could have Whites more
intense than yellows making
that colour stand out more in
the image changing it
dramatically. This can be
used to Create pictures that
invoke emotions such as a
picture heavily relying on
blue could be used to portray
sadness

8. Composition is basically
where everything in your
photograph is placed and
can alter the final
outcome of your image
greatly. If the background
is not an issue you can use
Photoshop to crop and fix
any issues regarding
placement of the central
subject.

9. The rule of thirds is a guideline where
the image is cut into 9 equal squares
with lines and the most important
features of a photograph must rest or
be on these lines. The rule of thirds is
applied by aligning a subject with the
guide lines and their intersection
points, placing the horizon on the top
or bottom line, or allowing linear
features in the image to flow from
section to section. The main reason
for observing the rule of thirds is to
discourage placement of the subject
at the centre, or prevent a horizon
from appearing to divide the picture in
half

10. Complementary colours are
colours that are opposite to
each other on the colour wheel
and can be used to create
striking images
Complementary Colours

11. Analogous colours are
groups of colours that are
together and blend from
each other on the colour
wheel (orange, orange-
yellow, Yellow)
