Abstract
The discussion on the production of prompt photons with p(T) similar to few GeV in the tagged processes ep --> e gamma X with small Q(2) at HERA is pr esented. Photons produced in the forward (proton) direction are mainly comi ng from subprocesses involving interaction of the gluonic content of the in itial photon. Therefore a possibility of extracting a gluonic density of th e real and of the virtual photon arises. The BFKL approach to the descripti on of the forward photon production is shortly discussed.
