Aperture (AV mode)
Aperture refers the depth of the field, or how far away the camera is in focus. It is measured
in f-numbers. A low f-number decreases the depth of the field, and only a small section of the
image will be in focus, so things in the distance appear blurry. So a high f-number means
things will still be in focus a long way away.
In this first picture you can see
everything is in focus.
Everything is mostly in focus,
thoughparts of the image are unclear,
the bag remains in focus.
The bag remains in focus, though things
around it and further away are not.
Shutter Speed (Tv mode)
Shutter speed is the length of time the shutter remains open after you press the button to
take the photo. A lower shutter speed captures movement as there is more time to capture it,
pictures taken on a low shutter speed will often come out blurry because of this.Ahigher
shutter speed does not capture movement as the length of time the shutter is open capturing
the image is much too fast, only capturing a split second.
Using a fast shutter speed for a moving
person stops the image from blurring. It
takes a darker image as there is
notmuchtime for the camera to capture
Fast Shutter Speed
Similarly to the first image with a fast
shutter speed, the image is still fairly
clear. Though there is some slight
blurriness beginning to show.
Medium Shutter Speed
A slow shutter speed has made the
walking person in the image appear
blurry. The things in the background that
are still are less clear than before. The
light is much brighter in this image as
more light has been allowed in through
Slow Shutter Speed
The ISO setting changed how sensitive the camera is to light. A higher number means it is
more sensitive, and will create noise. Noise is random variations of brightness or
colour.Therefore a lower number means the camera is much less sensitive to light and there
will be much less noise on the image. Noise is much more apparent on larger images than on
In this first image with a high ISO it appears
noisy. There are some flecks of random
colour in the image due to the cameras
sensitivity to light.
In this next image the camera is less sensitive
to light, and the noise has been reduced.
In this last image the the cameras sensitivity
to light has been reduced significantly, I can’t
see any noise in this image.
Changing the white balance helps the camera to understand what white is. Auto-white
balance will work for most situations when there is good lighting around, though whenitis too
blue or too yellow then sometimes the setting needs to be changed to balance it out.
Fluorescent Light Setting
The daylight setting appears natural, I cannot see any obvious colour distortion The
fluorescent light settingappears much more blue. Then thecloudy setting is much more
