This contribution discusses the measurements of direct photons in pp and Pb–Pb collisions from the LHC Run 2, as recorded by the ALICE experiment. Specifically, we focus on the isolated photons results obtained at √SNN = 5.02 TeV. The isolated photons γiso spectra in pp and Pb–Pb collisions are presented together with the nuclear modification factor, that is found to be consistent with unity. The azimuthal correlations of γiso with hadrons in Pb–Pb and the hadron zT distributions D(zT) are presented, showing a centralitydependent suppression compared to the pQCD NLO pp reference.
