Interactions between hadrons and photons constitute an important tool to explore the intrinsic structure of hadrons. At the same time, high-precision determinations of electromagnetic processes, as in particular ɡ − 2 of the muon, constitute a promising tool to look for the impact of beyond-standard-model physics. Here hadronic contributions constitute the main uncertainty for the standard-model prediction. In this talk results for electromagnetic transition form factors and two-gamma amplitudes are presented.
