Preliminary results will be presented from the first tagged photon experiments at Jefferson Lab. These experiments used the CLAS detector and the Hall B photon tagger to measure pion, kaon, and double pion photo-production cross sections on the proton. Over 400 million events were taken with a single charged hadron trigger over a tagged photon energy range from 0.5 GeV to 2.4 GeV. An additional 400 million events were taken with circularly polarized photons over an energy range from 0.36 GeV to 1.8 GeV. These data are yielding a wealth of new information in the area of nucleon and hyperon structure, and tests of chiral dynamics. Data will be presented on hyperon production with polarized and unpolarized photons, the radiative decay of hyperons, eta and eta' photo-production, the search for missing nucleon resonances in two pion photo-production, tests of the chiral axial anomaly, and measurements of single pion photo- production.
