Abstract
I discuss radiative corrections due to the emission of photons from qu arks which contribute to deep inelastic lepton-nucleon scattering as w ell as to pp collisions at high energies. These corrections are domina ted by quark-mass singularities which have to be absorbed into the par ton distribution functions. Observable effects appear as a modificatio n of the Q(2) dependence of the distribution functions. Numerical resu lts indicate, however, that these QED corrections are negligible excep t at extremely large Q(2) and large x. Therefore it is safe to neglect the single and multiple photon effects in pp scattering at CERN LHC e nergies.
