2. Resolution
This controls the amount of detail held in the
photograph
The higher the resolution the more detailed the image
will be
A higher resolution image is physically larger in size
and will take up more space on the memory card

4. Comparing settings
Take 3 photographs of the same thing using the
different resolution settings
Store the photographs in a folder called
Resolution
Explain any differences you can see in each of
the photographs e.g. file size, detail, clarity
5. Controlling Exposure
Exposure is the amount of light that is allowed to
fall on the image sensor
The two controls that affect exposure are
aperture and shutter speed
Which particular settings you choose depends on
the situation. If the subject is moving, and you
want to freeze the motion, choose the settings
with the fastest shutter speed. If the subject is
stationary and you want maximum clarity, choose
the settings with the smallest aperture (to
increase depth of field).
7. ISO Speed and Exposure
ISO affects the shutter speed / aperture
combinations you can use to obtain correct
exposure
ISO measures the sensitivity of the image sensor
Higher ISO settings are generally used in darker
situations to get faster shutter speeds (for
example an indoor sports event when you want to
freeze the action in lower light)
If there is not enough light you can increase the
ISO setting this can be done automatically or
manually
ISO settings in the Canon A460 are Auto, High,
8. Photographs
Take a selection of indoor photograph using a
range of different ISO settings
Compare the images
9. Macro mode
Macro mode is generally symbolized
with a little flower and when selected
it will tell your camera that you want
to focus on a subject closer to your
lens than normal
Macro mode will also usually tell your camera to choose a
large aperture so that your
subject is in focus but the
background is not
10. Macro mode
Take a selection of photographs using Macro
mode to demonstrate that you understand what it
is used for
