After a comparison of conventional photospheres with circumstellar envelopes the radiation in spherical shells is considered. We discuss the transfer equation and a new quasi-exact solution in term of the transition matrix-Various methods used for the numerical evaluation of the specific intensities are summarized. The general properties of the radiation fields and some recent detailed model calculations are briefly reviewed.
