 D calculations of photon production cross sections applied an idealised ph
 oton isolation procedure\, which differs from the isolation used in experi
 ments. We present first numerical results for NNLO QCD predictions of isol
 ated photon cross sections at the LHC with a realistic cone-based isolatio
 n. Photon fragmentation processes are included for the first time at NNLO\
 , by extending the antenna subtraction method to handle infrared-singular 
 parton-photon configurations while retaining the information on the photon
 ic energy inside the collinear parton-photon cluster. We describe how thes
 e singularities are subtracted in antenna subtraction using new fragmentat
 ion antenna functions and outline their integration.
