  Rho photoproduction on complex nuclei is re-examined using a generalised
vector dominance model which succesfully predicts the observed nuclear
shadowing in real photoabsorption and deep inelastic scattering. This model is
shown to give a good fit to rho photoproduction data on both nucleons and
complex nuclei, in which the well-known disagreement between the measured
gamma-rho coupling and the gamma-rho coupling required by the simple vector
dominance model is eliminated. The rho N total cross-sections required are
similar to those predicted by the additive quark model; and the magnitude of
the correction to simple vector dominance is consistent with that inferred from
the analysis of real photoabsorption and deep inelastic scattering.
