  The reactions $\gamma p\to\pi^0 p$ and $\gamma p\to\pi^+ n$ are analyzed in a
semi-phenomenological approach up to $E\sim2.3$ GeV. Fits to differential cross
section and single and double polarization observables are performed. A good
overall reproduction of the available photoproduction data is achieved. The
J\"ulich2012 dynamical coupled-channel model -which describes elastic $\pi N$
scattering and the world data base of the reactions $\pi N\to\eta N$,
$K\Lambda$, and $K\Sigma$ at the same time - is employed as the hadronic
interaction in the final state. The framework guarantees analyticity and, thus,
allows for a reliable extraction of resonance parameters in terms of poles and
residues. In particular, the photocouplings at the pole can be extracted and
are presented.
