We consider photoproduction of vector mesons and Compton scattering at high energies. Coupling of the electromagnetic current to neutral vector mesons as given theoretically in quark models and experimentally in storage-ring experiments is assumed. This gives a reasonable theory for rho, ..omega.., phi, psi, and psi' photoproduction processes in a unified manner with appropriate energy dependence for (dsigma/dt)/sub 0/ for phi, psi, and psi', as well as for the slope parameter while approaching the high-energy limit. The correct total Compton-scattering cross section by nucleons in the high-energy limit is obtained. It appears that one is able to understand in a qualitative manner the success of vector-dominance models in the context of the quark model, without assuming vector dominance in a conventional form and without any field-current identity.
