The production of prompt photons is measured in photoproduction of e-p scattering at HERA. The analysis is based on data from total luminosity 340 pb-1 collected by H1 experiment. Cross section is measured for photons with transverse energy 6 < ET <15 GeV and pseudorapidity -1.0 < eta < 2.4. Cross sections for events with an additional jet are measured as a function of transverse energy and pseudorapidity of the jet and as a function of x_gamma and x_p carried by partons entering the hard process. The results are compared with QCD predictions.
