We present analysis of both the inclusive and the direct photon yields in the low-to-mid pT range at mid-rapidity in Au+Au minimum bias collisions at √sNN = 200GeV for the PHENIX 2004 dataset. The measurement employed a novel tagging technique in which a photon sample of high purity is generated using a stringent charged particle veto and tight fiducial cuts.
