description In high energy hadron collisions, direct photons can be produced in various processes and are of particular interest to study the hot QCD medium since they escape it without being affected. In these proceedings are presented the latest ALICE experiment results concerning direct photon production in proton-proton (pp), proton-lead (p-Pb) and lead-lead (Pb-Pb) collisions. All measurements agree with pQCD calculations at high transverse momentum ($p_{\text{T}}$) and show no direct photon excess at low $p_{\text{T}}$ in small systems while a low $p_{\text{T}}$ signal is found in central Pb-Pb collisions.
