  The hard photon productions from bremsstrahlung and annihilation with
scattering that arise at two loop level are estimated from a chemically
non-equilibrated quark gluon plasma using the frame work of thermal field
theory. Although, the rate of photon production is suppressed due to
unsaturated phase space, the above suppression is relatively smaller than
expected due to an additional collinear enhancement (arise due to decrease in
thermal quark mass) as compared to it's equilibrium counterpart. Interestingly,
unlike the one loop case, the reduction in the two loop processes are found to
be independent of gluon chemical poential, but strongly depends on quark
fugacity. It is also found that, since the phase space suppression is highest
for annihilation with scattering, the photon production is entirely dominated
by bremsstrahlung mechanism at all energies. This is to be contrasted with the
case of the equilibrated plasma where annihilation with scattering dominates
the photon production particularly at higher energies.
