White balance has to do with matching the colour response of your
editing software with the colour temperature of the dominant light
source in your scene. You need to know that the usual light source
suspects all give off light of different hues, based on their native
colour temperature. For
A gray card gives your camera or the white balance tool in LR a single point of
reference to adjust the RGB mix to a neutral balance. But flourescents are not
