“Photometry” deals with measurement of light; it’s not clear what you mean when you use this term.
White balance is simply a means of defining white for the camera’s circuitry. It’s also possible to white balance in many NLE editing programs, defining white for the program’s color correction utility.
Manual white balance in camera is pretty straight-forward: Using the lighting that you will be shooting with, set up a white card (paper, cardboard, etc.,) and zoom in until the card entirely fills the viewfinder. Press the white balance button on the camera, wait until the white balance icon stops flashing, and you’re finished.
Be sure to white balance each time you change lighting setups.
