  In this work, we assess the importance of non-equilibrium dynamics in the
production of photons from the late stages of relativistic heavy-ion
collisions. The p$_\mathrm{T}$-differential spectra and $v_2$ of photons from
the late hadronic stage are computed within a non-equilibrium hadron transport
approach, and compared to the results of a local equilibrium evolution using
ideal relativistic hydrodynamics. It is found that non-equilibrium dynamics
enhance the late-stage photon production at low p$_\mathrm{T}$ and decreases it
at higher p$_\mathrm{T}$ compared to the estimate from hydrodynamics. This same
comparison points to a significant increase in the momentum anisotropies of
these photons due to non-equilibrium dynamics. Once combined with photons
produced above the particlization temperature in the hydrodynamics evolution,
the differences between the two approaches appear modest in what concerns the
p$_\mathrm{T}$ differential spectra, but are clearly noticeable at low
p$_\mathrm{T}$ for the elliptic flow: non-equilibrium dynamics enhance the
photon $v_2$ below p$_\mathrm{T}$ $\approx 1.4$ GeV.
