• We study the application of the dual theory of hadron electromagnetic currents to meson photoproduction. The "statistical approximation" of Chang, Freund and Nambu to the dual resonance model is used for calculating the Born approximation Feynman graphs. A technique for constructing gauge-invariant amplitudes in the limit of statistical approximation to the dual amplitudes is developed. It is found that the vector-meson photoproduction amplitude in this model has similar properties to those of the vector-meson dominance model based on the photon vector analogy. The model developed is applied to data of the process γp→ρ^0p The fit to ρ photoproduction differential cross-section allows us to estimate the charge distribution weight function of the dual hadrodynamics.
