  We calculate the cross section of charm photoproduction at HERA collider in
the framework of the kt-factorization QCD approach. Our analysis cover the
inclusive charm production as well as charm and associated jet production
processes. Both photon-gluon and gluon-gluon fusion mechanisms are taken into
account. The unintegrated gluon densities in a proton and in a photon obtained
from the full CCFM, from unified BFKL-DGLAP evolution equations as well as from
the Kimber-Martin-Ryskin prescription are used. Our theoretical results are
compared with the recent experimental data taken by the H1 and ZEUS
collaborations at HERA. Special attention is put on the specific angular
correlations which can provide unique information about non-collinear gluon
evolution dynamics.
