We consider a model for the decay B 0 → ρ 0 γ in which the short-distance amplitude determined by the Hamiltonian describing b → dγ is combined with a typical long-distance contribution B 0 → D + D − → ρ 0 γ. The latter possesses a significant dynamical phase which induces a CP-violating asymmetry A CP , as well as an important modification of the Stokes vector of the photon.
