Depth of field uses blur to focus on specific parts of an image, bringing the viewer into the photograph. Shutter speed controls how fast an image is captured - a longer shutter speed blurs motion while a shorter shutter speed captures more detail. Aperture controls the amount of light in an image; adjusting the aperture and ISO helps create a clear picture by finding the right balance of lighting.

1. Depth of Field
Depth of field is used to bring you into the
photograph. It uses blur to take out the
focus in parts of the composition, making
the section that is in focus more visible. By
using it you can use the manual focus at
the end of the lens. Using the depth of field
on auto, the blur wont be as strong
because it doesn’t know what you want in
focus.

2. Shutter Speed
Shutter speed controls how fast a
photo is taken. Taking pictures of
people running, to get the ‘motion
blur’ you would want the shutter
speed to last longer to capture
more light. If you wanted to take a
picture of a pebble dropping into
water and wanted to get more
detail than movement, a shorter,
quicker shutter speed would be
best to get this shot.

3. Aperture
Aperture is used to control how
much light is in the picture. Too
much light is ‘over exposed’ this
makes the picture too bright,
therefore takes out the detail.
Finding the right aperture
depends on the lighting. To create
a clear picture, adjusting the ISO
will help do this. The aperture is
the size of the opening on the
lens, allowing more or less light
in.
