  We present a calculation of the generalized parton distributions (GPDs) of
the photon when the helicity of the initial photon is different from the final
photon. We calculate the GPDs using overlaps of photon light-front wave
functions (LFWFs) at leading order in electromagnetic coupling $\alpha$ and
zeroth order in the strong coupling $\alpha_s$, when the momentum transfer is
purely in the transverse direction. These involve a contribution of orbital
angular momentum of two units in the LFWFs. We express these GPDs in the impact
parameter space.
