  This Letter presents measurements of l nu gamma and l^+ l^- gamma (l=e, mu)
production in 1.02 fb^-1 of pp collision data recorded at sqrt(s) = 7 TeV with
the ATLAS detector at the LHC during 2011. Events dominated by W gamma and Z
gamma production with leptonic decays of the W and Z bosons are selected, and
their production cross sections and kinematic properties are measured in
several ranges of the photon transverse energy. The results are compared to
Standard Model predictions and are used to determine limits on anomalous
W-W-gamma and Z-Z-gamma/Z-gamma-gamma couplings.
