  We revisit the application of the Froissart-Gribov (FG) projections in the
analysis of amplitudes for the Deeply Virtual Compton Scattering (DVCS),
providing essential information on generalized parton distributions (GPDs). The
pivotal role of these projections in a systematic description of a hadron's
response to the string-like QCD probes characterised by different values of
angular momentum $J$ is emphasised. For the first time, we establish a
relationship between the FG projections and GPDs for spin-$\frac{1}{2}$
targets, and we investigate these quantities in various GPD models. Finally, we
provide the first numerical estimates for the FG projections based on the DVCS
amplitudes directly extracted from experimental data. We argue the method of
the FG projections deserves a broad application in the DVCS phenomenology.
