Two charged pion final states are studied for GeV photons incident on protons. The data come from Thomas Jefferson National Accelerator Facility using the CLAS detector. A tagged photon beam of 0.5-2.4 GeV/c was produced through bremsstrahlung radiation and was incident on a liquid H2 target. This analysis looks at the reaction γ p → p π^+ π^- using a partial wave analyis to identify intermediate baryon resonances. Total cross section is compared to previous experiments and preliminary
