Description: "Doppler boosting / de-boosting" is a well-known relativistic effect that alters the apparent luminosity of approaching/receding radiation sources. While "Doppler boosting / de-boosting" has been successfully accounted for and observed in relativistic jets of AGN, double white dwarfs, pulsars, in search of exoplanets and stars in binary systems, it was ignored in the analysis of radiation near strong gravitational objects (e.g. black holes.) The de-boosting factor as a function of gravitational redshift z allows to build the de-boosting diagram, which matches with the observed images of black holes
