Photon redshift and the appearance of a naked singularity

In this paper we analyze the redshift as observed by an external observer receiving photons which terminate in the past at the naked singularity formed in a Tolman-Bondi dust collapse. Within the context of models considered here it is shown that photons emitted from a weak curvature naked singularity are finitely redshifted to an external observer whereas the strong curvature naked singularities are censored in the sense that photons escaping in such a scenario are infinitely redshifted.
