Understand what white balance is and how it
affects your digital camera's picture will help you a lot to photograph a more
desirable photo. Most cameras have a white balance control, and will have all
or some of the following settings:
Automatic
white balance
|
The
camera will analyse the image and set the white balance automatically.
|
Daylight
|
This
is for shooting in direct sunlight.
|
Cloudy
light
|
The
light on an overcast day is somewhat cooler (bluer) than it is in direct
sunlight, so this setting compensates by warming the photograph.
|
Shade
|
Subjects
in shady areas will be slightly bluer than daylight, so this setting
compensates by warming the colours even more. You can also use this setting
to get warm colours even in daylight.
|
Flash
|
Flash
light is slightly cooler than daylight, using this setting will warm the
picture a tiny bit compared to the "Daylight" setting. This only
applies for situations in which the flash is the sole source of
lighting.
|
Tungsten
|
Light
from tungsten bulbs is substantially more orange than daylight, so the camera
compensates by adding blue to the picture.
|
Fluorescent
light
|
Fluorescent
lamps are somewhat redder than daylight (less so than tungsten bulbs,
however), so this setting will compensate by cooling the picture.
|
Preset
white balance
|
This
is often the only way of getting good results under "energy saving"
lighting. It can often get more accurate results under artificial lighting
than the white balance settings dedicated to that kind of lighting.
|
Manual
white balance
|
This
allows you to specify a color temperature for which to correct.
|
Setting this differs from camera to camera,
so read your manual. Some compact cameras
lack white balance settings entirely and put them as scene modes. You'll have
to figure out the effects yourself. A "Foliage" mode will typically
bias the colors towards green, "Sunset" will make them warm, and “Fall
Foliage" will also warm the picture.
Left to right: automatic, tungsten and preset white balance settings. The preset setting has much more accurate colors. |
