  We consider the electromagnetic decays of the orbitally-excited SU(6) 70-plet
baryons, to compare the predictions of the naive quark model with those of
large-N_c QCD. The helicity amplitudes measured in N^* photoproduction are
computed in a large-N_c effective field theory, based on a Hartree
approximation, and the amplitudes are fit to the current experimental data. Our
results indicate that the success of the naive quark model predictions cannot
be explained by large-N_c arguments alone. This is consistent with the
conclusions of an earlier study of the N^*\to N\pi decays, that utilized the
same approach.
