We studied the radiative transfer in a spherical, two-phase clumpy medium, in which coherent, nonconservative scattering is the dominant opacity source and where the source of photons is situated at the center. ... We examined in detail the cloud mass spectrum, the distribution of optical depths, and the apparent fractal nature of the projected cloud structures. ... The expected reddening is substantially reduced for clumpy media. ...
