The process of pair photoproduction in an electromagnetic field of arbitrary configuration is investigated. At high energy the correction to the standard quasiclassical approximation (SQA) of the process probability has been calculated. In the region of intermediate photon energies where SQA is inapplicable the new approximation is used. The influence of weak electric field on the process in a magnetic field is considered. In particular, in the presence of this field the root divergence in the probability of pair creation on the Landau energy levels is vanished. For smaller photon energies the low energy approximations have been derived. At very low photon energy the found probability describes the absorption of soft photon by the particles created by the field. At low photon energy the electric field action dominates and the influence of the magnetic field on the process occurs because of its interaction with the magnetic moment of creating particles.
