Abstract
A method of quantizing the electromagnetic field is proposed, where the underlying Hilbert space has a definite metric and the verifications of Lorentz covariance can be easily carried out with the help of Ward's identity. The usual Feynman-Dyson rules are obtained for the electron-photon system, and the longitudinal and scalar photons are found to have separately no interaction with the electron field.
