I will present a study of the electromagnetic properties of light and heavy baryons in a relativistic quark model. The relativistic quark model is based on a phenomenological Lagrangian coupling light and heavy baryons to their constituent quarks. I will concentrate on the calculation of the bare contributions to the magnetic moments of single-, double- and triple-heavy baryons. For the light sector, a Lorentz covariant chiral quark Lagrangian is used to dress the constituent quarks by pseudoscalar meson clouds. I will discuss the magnetic moments of light baryon octet and elaborate on the N --> Delta gamma transition properties, including pseudoscalar meson corrections.
