  In this paper, we extend the study of bremsstrahlung photon production in a
quark-gluon plasma to the cases of soft static photons and hard real photons.
The general framework of this study is the effective perturbative expansion
based on the resummation of hard thermal loops. Despite the fact that
bremsstrahlung only comes at two loops, we find that in both cases it generates
contributions of the same order of magnitude as those already calculated by
several other groups at one loop. Furthermore, a new process contained in the
two-loop diagrams dominate the emission of a very hard real photon. In all
cases, the rate of real or virtual photon production in the plasma is
appreciably increased compared to the one-loop predictions.
