Abstract: The quantization of the electromagnetic field in vacuum is presented without reference to Lagrangian quantum field theory. The equal-time commutators of the fields are calculated from basic principles. A physical discussion of the commutators suggests that the electromagnetic fields are macroscopic emergent properties of a more fundamental physical system: the photons.
