A general review of the electromagnetic properties of the hadrons when interpreted as composite states of quarks is given. Electromagnetic mass formulas are derived using two-body forces. The one-particle contributions to the magnetic moments of the baryons and to the electromagnetic decays of the vector mesons are calculated without any assumptions about the U-spin transformation properties of the photon. The electromagnetic decays of the spin-32 baryons are calculated in a way analogous to the Becchi-Morpurgo calculation of the rate for ω-->π0γ. A quark model of photoproduction is presented, and its predictions are accompanied by the explicit kinematic correction factors necessary for a comparison with experiment.
