We consider the electromagnetic decays of the orbitally-excited SU(6) 70-pletbaryons, to compare the predictions of the naive quark model with those oflarge-N_c QCD. The helicity amplitudes measured in N^* photoproduction arecomputed in a large-N_c effective field theory, based on a Hartreeapproximation, and the amplitudes are fit to the current experimental data. Ourresults indicate that the success of the naive quark model predictions cannotbe explained by large-N_c arguments alone. This is consistent with theconclusions of an earlier study of the N^*\to N\pi decays, that utilized thesame approach.Comment: 17 pages LaTeX, four EPS figure
