We calculate the effect of a Dirac point (a conical singularity in the band structure) on the transmission of monochromatic radiation through a photonic crystal. The transmission as a function of frequency has an extremum near the Dirac point, depending on the transparencies of the interfaces with free space. The extremal transmission T0=\ensuremathΓ0W∕L is inversely proportional to the longitudinal dimension L of the crystal (for L larger than the lattice constant and smaller than the transverse dimension W). The interface transparencies affect the proportionality constant \ensuremathΓ0, and they determine whether the extremum is a minimum or a maximum, but they do not affect the ``pseudodiffusive'' 1∕L dependence of T0.
