  We have applied a new approach to determine the pole positions and residues
from pion photoproduction multipoles. The method is based on a Laurent
expansion of the partial wave T-matrices, with a Pietarinen series representing
the regular part of energy-dependent and single-energy photoproduction
solutions. The method has been applied to multipole fits generated by the MAID
and GWU/SAID groups. We show that the number and properties of poles extracted
from photoproduction data correspond very well to results from $\pi$N elastic
data and values cited by Particle Data Group (PDG). The photoproduction
residues provide new information for the electromagnetic current at the pole
position, which are independent of background parameterizations, as opposed to
the Breit-Wigner representation. Finally, we present the photo-decay amplitudes
from the current MAID and SAID solutions at the pole, for all four-star nucleon
resonances below W=2 GeV.
