We present results for the photoproduction helicity amplitudes of excited baryons obtained in the context of the 1/N_c expansion of QCD. The results show that, in order to get a satisfactory description of the observed photoproduction amplitudes, the sub-leading corrections in 1/N_c are important. We also find that, while onebody effective operators are dominant, there is some evidence for the need of two-body effects which, in general, are not included in quark model calculations.
