A relativistic calculation of photon-nucleon elastic scattering in the energy range from 0 to 450 MeV in the laboratory is presented. It includes explicit contributions from s- and u-channel nucleon intermediate states, t-channel neutral pion states, and s-channel delta resonance states. Other processes are implicitly included via energy-dependent parameters in the resonance process. Comparison with experiments show an improvement over similar nonrelativistic approaches.
