At moderate and large momentum transfer, high energy vector-meson photoproduction and Compton scattering can be consistently explained by mechanisms based on interactions and exchanges of constituent quarks and gluons. This opens an original window to the partonic structure of hadronic matter by emphasizing the role of quark correlations, quark exchange as implemented through saturating Regge trajectories, and nonperturbative effects in the gluon propagator, which provides us with a bridge to lattice calculations. Compton scattering is directly related to vector-meson photoproduction and enlarges the data set.
