Branching ratios for photoproduction of vector mesons and strange particles are discussed. The one-pion-exchange mechanism cannot explain the observed ratio between p and w photoproduction cross-sections. Various versions of pseudo elastic mechanisms are studied and it is shown that although they correctly predict the large p:w production ratio, they cannot account for the extremely small preliminary cross-section for cp production. It is shown that no combination of one-pion-exchange and the diffraction mechanism with exact or broken SU(3) can explain the low cp production rate. The multiperipheral model may explain the low Q production, but predicts the wrong p:w production ratio. Various possible sources of this discrepancy are studied and experimental tests are discussed which can distinguish between the different proposed theories. A large number of new predictions based on exact or broken SU(3) symmetry are derived, presented and compared with experiment.
