atchina analysis of photoproduction data ECT workshop, Trento 3.6-4.7.4 SUMMARY The new polarized data on π photoproduction confirm the Bonn-Gatchina solution below GeV and provide an important information about resonances in the mass region -.3 GeV. The new data on double meson photoproduction were successfully fitted. The vector photoproduction data provide an important constraint for the combined analysis and reveal signals from resonances above GeV. However... A large amount of new data will be available soon and it looks like they are not well predicted by any model: new discoveries will come soon. 53
