Note that it is not possible to improve the signal-to-noise ratio by increasing gain. Increasing the
gain will increase both signal and noise in equal proportions.
White Balance:
If you are using a color camera, the object that you use when adjusting the white balance
should be a uniform gray and should fill the camera's entire field of view. Your white balance
will be correct when images of this object show a uniform gray.
Changing the black level setting will change the white balance. We therefore recommend that
you check the white balance after setting the black level.
Make sure the image is neither underexposed nor overexposed when checking the white
balance.
