  We calculate medium photons due to Compton and annihilation processes in an
anisotropic media. The effects of time-dependent momentum-space anisotropy of
{\em Quark-Gluon-Plasma} (QGP) on the medium photon production are discussed.
Such an anisotropy can results from the initial rapid longitudinal expansion of
the matter, created in relativistic heavy ion collisions. A phenomenological
model for the time-dependence of the parton hard momentum scale,
$p_{hard}(\tau)$, and anisotropy parameter, $\xi(\tau)$, has been used to
describe the plasma space-time evolution. We find significant dependency of
photon yield on the isotropization time ($\tau_{iso}$). It is shown that the
introduction of early time momentum-space anisotropy can enhance the photon
production by a factor of $10 (1.5)$ (in the central rapidity region) for {\em
free streaming} ({\em collisionally-broadened}) {\em interpolating} model if we
assume fixed initial condition. On the other hand, enforcing the fixed final
multiplicity significantly reduces the enhancement of medium photon production.
