A measurement of the charm and beauty photoproduction cross sections at the ep collider HERA is presented. The lifetime signature of c and b-flavoured hadrons is exploited to determine the fractions of events in the sample containing charm or beauty. Differential cross sections as a function of the jet transverse momentum, the rapidity and x{sub {gamma}}{sup obs} are measured in the photoproduction region Q2 < 1 GeV2, with inelasticity 0.15 < y < 0.8. The results are compared with calculations in next-to-leading order perturbative QCD and Monte Carlo models as implemented in PYTHIA and CASCADE.
