White balance is a camera concept relates to
capturing the true color of a subject when the scene is affected by artificial
light. In simpler words, it is a way of adjusting the colors to make it more
similar to the image that we saw upon taking the picture. Usually, different light sources interfere
the real “white” color and may have definite “color temperature” that’s why,
white balance is necessary in photography in order to bring out the natural
color of the image.
