  The light front densities of momentum, angular momentum, and intrinsic
pressure are calculated for the photon, both in the free case and at leading
order in quantum electrodynamics. In the latter case, we moreover decompose the
form factors into photon and electron contributions. Circularly and linearly
polarized photons are both considered, with the latter containing significant
azimuthal modulations in both the momentum density and in intrinsic stresses.
We find that the D-term of the photon is positive instead of negative, and
accordingly the intrinsic radial pressure of the photon is negative. Despite
this, the radiation pressure exerted by the photon is positive. We illustrate
through explicit calculation how the intrinsic pressure associated with the
D-term and the radiation pressure exerted by the photon are different
quantities.
