  In this contribution, we review the results of the recent paper "The photon
PDF from high-mass Drell Yan data at the LHC" (arXiv:1701.08553), where a
determination of the photon PDF from fits to recent ATLAS measurements of
high-mass Drell-Yan dilepton production at centre-of-mass energy of 8 TeV is
presented.
