Results of a next-to-leading order calculation of the inclusive cross sectionfor a photon and a heavy quark (charm or bottom), $p \bar p / pp \to \gamma +Q+X$, are presented. Pointlike photon subprocesses through ${\calO}(\alpha\alpha_{s}^2)$ and fragmentation subprocesses through ${\calO}(\alpha_{s}^3)$ are included. The calculation is performed using a phasespace slicing technique so that the effects of experimental cuts can beincluded. Results for the ratios of the charm and bottom cross sections arepresented and the systematics of the various subprocesses for both the Tevatronand the LHC are compared and contrasted.
