Abstract
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 = 5.02 TeV. The isolated photons 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 with hadrons in Pb--Pb and the hadron distributions are presented, showing a centrality-dependent suppression compared to the pQCD NLO pp reference.
