Exclusive photoproduction of all vector mesons by real and virtual photons is considered in the Soft Dipole Pomeron model. It is emphasized that being the Pomeron in this model a double Regge pole with intercept equal to one, we are led to rising cross-sections but the unitarity bounds are not violated. It is shown that all available data for ρ, ω, φ J/ψ and Υ in the region of energies 1.7 normal subgroup of or equal to W normal subgroup of or equal to 250 GeV and photon virtualities 0 normal subgroup of or equal to Q2 normal subgroup of or equal to 35 GeV2|, including the differential cross-sections in the region of transfer momenta 0 normal subgroup of or equal to |t| normal subgroup of or equal to 1.6 GeV2,| are well described by the model.
