Why do we normalize RGB?

At times, you want to get rid of distortions caused by lights and shadows in an image. Normalizing the RGB values of an image can at times be a simple and effective way of achieving this. When normalizing the RGB values of an image, you divide each pixel’s value by the sum of the pixel’s value over all channels.
