Why it matters
Wrong or changing white balance makes skin look odd and clips look mismatched.
Example
Lamp light looks orange and shade looks blue until the white balance is matched to them.
Common mistake
Mixing a warm lamp with cool window light on the same face.
How to use it
Phones set white balance automatically and can drift mid-shot as you move. For consistent clips, use one kind of light (turn off the lamps when filming by a window), and if your camera app allows it, lock white balance before you start. Small differences can be fixed in the edit with color correction, but big mixed-light problems usually can’t.
