  Some applications of the elementary kaon photoproduction process are
discussed: the investigation of missing resonances in the p(gamma,K+)Lambda
channel, the role of the P_{13}(1720) state in the p(gamma,K0)Sigma+ channel,
and the calculation of the Gerasimov-Drell-Hearn sum rule. For the latter, we
present an extension of our previous study to higher energies.
