My book and the computer screen is white, but under the flouriscent light become blue and yellow.
What is White Balance
Getting your whites white...
and I am not talking about the laundry.
White Balance (WB) in photography has to do with the accuracy of color in your image.
You might notice an image has a blue or orange cast to it..
for example the white snow might look bluish.
If you increase saturation,
you will increase the color casts as well.
Different sources of light have different color temperatures.
So white does not always look white in your photos.
While your eye naturally adjusts to the light temperature,
your camera tries to adjust, but may not always adjust correctly.
While choosing the correct white balance will enhance
the appearance and accuracy of your images,
it is critically important when shooting people.
Skin tones that look too blue or too orange are not only inaccurate,
but also not very flattering.
Here's How...
Digital Cameras have white balance settings.
While most of the time I shoot in the Auto White Balance (AWB) setting mode
which allows the camera to choose the color temperature,
I also shoot RAW so I can easily correct incorrect white balance settings.
At other times, when I am shooting in the same light environment,
I might adjust my white balance settings as follows.
