  Bose condensed light can form new phases [1] in a dye filled cavity due to
the presence of the orientational disorder created by dye molecules which are
essentially frozen on the time scale of the photonic thermalization (few ps).
At longer times (few ns) molecular degrees of freedom -- orientations and
positions -- become important. Including them on equal footing with photons can
change the nature of the photonic condensation -- it can proceed as Ist order
phase transition which can also result in the mutual phase separation effect --
for photons and dye. The analysis is conducted within the mean field approach
in the thermodynamic limit. Recommendations for the experimental detection of
the transition nature are formulated.
