2. Shutter Speed is the length of time that the
shutter on the camera lens stays open for
as this time will change the amount of light
and exposure that will show up on the
image that you have taken, you can decide
yourself how long you want to keep the
shutter open for depending on what type
of image you aim to capture.
The first image was took as a train was
going by, second were little garden
windmills and the last one was a picture of
late night traffic all the pictures have been
taken whilst I has been dark as this is when
it works best.
3. This is how sensitive a film is to the
light depending on what the ISO
number has been set at. A way to
explain this is: the lower the
number, the lower the sensitivity
which means that the grain will
appear finer in the shots you have
taken.
This is shown in these images.
4. The way a subject looks in a photograph
sometimes changes and can look different to
what the subject looked like to you when you
decided to take the picture, this is because
when you look at a scene everything in it looks
more or less equally sharp but sometimes in the
shot only part of the subject or part of the
picture appears sharp this is what is called the
Depth Of Field and it extends in front of and
behind the point that you focused on.
5. When the camera has been set in
manual mode the photographer will
just have to adjust the lens aperture
and/or the shutter speed this is in
order to achieve whatever kind of
exposure it is that they want.
6. Exposure is the amount of light that
you choose to allow to hit either a
subject or a specific area in the
picture you are taking. When a
camera has been set in automatic
exposure it automatically calculates
and adjusts the exposure settings to
match the subjects mid tone to the
mid tone of the object that you have
chosen to capture.

7. Colour is the global
adjustment of the
intensities of certain
colours, an important
goal of this adjustment is
to render specific colours
these are usually the
neutral colours. The
general method is usually
called grey
balance, neutral balance
or white balance.
8. This is the process where
you remove any
unrealistic colours from
the picture this is done to
ensure that objects that
will for example appear
white in person are
rendered so that they still
appear just as white in
your picture.
10. This applies to the process
of composing visual
images. The guideline says
that an image should be
imagined as being divided
into 9 equal parts.
11. These are clours that are next
to each other on the colour
wheel, these colours tend to
look good together because
they are closely related such as
colours like orange and yellow
for example.
12. These are pairs of colours that
are classed as being opposite
from each other.
Such as purple and violet which
are both used together in the
picture of the flower.
13. This is usually used for when you
want to take pictures of very small
objects as it is extreme close up
photography so that the subject
that has been photographed
appears bigger in the photograph
that it actually is in real life.
