Flash. This is color balanced for
using the built-in flash and Sony
external flashes. This setting can
be fine-tuned by 3 stops, where
adding increases the red tone and
decreasing reduces the red tone.
✦
Color temperature / Color filter.
The white balance can be set using
a color temperature. The color
temperature can be set between
2500K and 9900K. Once the color
temperature is set, it can be
adjusted from Green (G) to
Magenta (M) the same way a color
compensation filter is used in film
photography. There are a total of
18 steps of adjustments, 9 for
green and 9 for magenta.
Color temperature is covered in
greater detail in Chapter 4.
✦
Custom white balance. Using a
Custom white balance is great for
scenes with multiple types of light.
The A700 lets you store three
Custom white balance settings,
each one accessible from the
White Balance menu.
Setting a Custom white balance
is covered in Chapter 2.
The white balance can be
changed with software after the
photo has been taken. This
used to only be possible when
the photo was taken in the RAW
format. With the release of
Adobe Photoshop CS3, it is now
possible to change the white
balance on JPEG files as well.

Images taken in the wrong white balance can cause dramatic color shifts. This image
was taken with the white balance set to AWB (Auto White Balance) which rendered great
colors.
