In this contribution we discuss recent progress in associated top-quark pair production with one or two isolated photons, $pp\to t\bar{ t}\gamma(\gamma)$. The focus is the simultaneous inclusion of higher-order effects and photon radiation in the production of the top-quark pair and in the decay processes. This allows us to quantify the importance of photon radiation in decay processes and the size of the so-called complete NLO corrections in realistic final states.
