  We report on the performance studies of two correction methods, namely the
efficiency-purity method and the Bayesian unfolding method applied to the
pseudorapidity distribution of photons. The pseudorapidity distribution of
inclusive photons at forward rapidities in the range \mbox{\small
$(2.3<\eta<3.9)$} in p\textendash Pb collisions at $\sqrt{\it{s}_{\rm{NN}}} =
8.16$ TeV is obtained with the HIJING Monte Carlo event generator. The
simulated data samples were obtained from the Photon Multiplicity Detector
(PMD) in ALICE.
