  Photons produced in the pre-equilibrium/pre-hydro stage of the quark-gluon
plasma produced in relativistic heavy-ion collisions were computed using parton
distribution functions obtained from solutions of the Boltzmann equation. The
effect of the initial gluon momentum anisotropy $\xi$ and the dependence on the
saturation momentum $Q_s$ was investigated. We see that small $Q_s$ results in
a photon yield enhancement, whereas a larger $Q_s$ results in a pre-equilibrium
photon suppression, owing to the strict constraint of matching to experimental
energy density.
