Abstract
In this talk some of the theoretical aspects of $b \to s γ$ transitions are discussed. The focus is on inclusive decays, since these can be computed more reliably. Topics covered are (1) perturbative QCD corrections, (2) non-perturbative contributions and (3) effects of ``new physics'' in these decays.
