An energy-dependent partial-wave analysis of pion photoproduction data through the second-resonance region (0--1 GeV laboratory kinetic energy) is presented. A set of energy-independent analyses has also been obtained starting from the energy-dependent solution. The data set contains 9074 data for the reactions {gamma}+{ital p}{r arrow}{ital p}+{pi}{sup 0}, {gamma}+{ital p}{r arrow}{ital n}+{pi}{sup +}, {gamma}+{ital n}{r arrow}{ital n}+{pi}{sup 0}, {gamma}+{ital n}{r arrow}{ital p}+{pi}{sup {minus}}, and the inverse reaction {pi}{sup {minus}}+{ital p}{r arrow}{ital n}+{gamma} (converted to {gamma}+{ital n}{r arrow}{ital p}+{pi}{sup {minus}}). The predictions of our solutions are compared with the results of previous analyses. Suggestions are made for future experiments.
