Direct photons provide an excellent probe in studying both the proton and nucleus collisions. The PHENIX measurements of the direct photon-hadron and neutral pion-hadron correlations in p+p collisions searches for the breakdown of the QCD factorization. The measurements of the fragmentation functions in Au+Au collisions provide an excellent tool to understand the dynamics of the energy loss mechanism in the heavy ion collisions. Furthermore, we summarize the results on the direct photon measurements at low-pT in order to study the thermal radiation in Au+Au and Cu+Cu collisions at different collision energies.
