    The LHC provided pp collisions in the energy range s=0.9to13TeV, p-Pb collisions at sNN=5.02and8TeV, as well as Pb-Pb collisions at sNN=2.76and5.02TeV. Neutral meson production spectra and their ratios η/π0 as well as photon double ratio Rγ and direct photon spectra have been measured in a wide pT range at mid-rapidity by the ALICE experiment. Photons are registered in ALICE electromagnetic calorimeters, EMCal and PHOS or reconstructed from e+e− pairs when photons converted in the material of the inner barrel detectors (TPC and ITS). The π0 and η mesons are reconstructed via invariant mass technique with several complementary methods. The overview of the recent results from ALICE on the photon and meson production is presented.
