Some selected topics in photoproduction are reviewed. In particular, the focus is on quasi-real photon–proton scattering as measured at HERA. Single & dijet rates and jet profiles are discussed, as are open charm production and inelastic charmonium production. The many intriguing theoretical issues which can be addressed through study of these processes are highlighted.
