This graphic is very helpful for all the beginner in Photography and filmmaking. This is something which comes in play after exposure. Because even if you have correct exposure for your shot but if you mess up with the White balance then you never gonna get nice looking colors. Auto white balance is crap. Ditch it. And atleast start with the presets given in your Cameras. Even now a days in phones they give option to control white balance. Use it and see the difference. :)
