Description
We present the latest ATLAS measurement of the cross section for the
inclusive production of isolated prompt photons of $pp$ collisions at
a centre-of-mass energy $\sqrt{s}$ = 7 TeV, as well as the measurement
of diphoton production. Photon candidates are identified by combining
information from the calorimeters and from the inner tracker. Residual
background in the selected sample is estimated from data, based on the
observed distribution of the transverse isolation energy in a narrow
cone around the photon candidate. The results are compared to
predictions from next-to-leading order perturbative QCD calculations.
