  The discussion on the production of prompt photons with pT of a few GeV in
the tagged process ep -> e gamma X with small Q^2 (DIC process) at the HERA
collider is presented. Photons produced in the forward (proton) direction are
mainly originating from subprocesses involving interactions of the gluonic
content of the exchanged photon. The large enhancement over the Born term
(direct photon) is found up to a factor of 35 for a real photon and up to 5 for
a virtual photon with a squared virtuality 1 GeV^2. It gives a possibility of
extracting a gluonic density of the real and of the virtual photon. The BFKL
approach to the description of the forward particle production is shortly
discussed.
