Book excerpt: Measurements by the Fermilab D0 and CDF collaborations of prompt photon events in p{anti p} collisions at √s = 1.8 TeV are reported. The measured isolated photon cross sections are compared to current parton distribution functions and NLO QCD predictions. The cross section ratio of forward to central [eta] bins and [eta] distributions are presented and compared with theoretical predictions. [gamma]+2jet events yield insight into final state radiation. A new measurement of [gamma]+[mu] events is presented which probes the charm content of the proton. Finally, di-photon results are presented as a probe of initial state radiation; these results are compared to NLO QCD, Pythia parton showers, and resummation models.
