Given a finite set X and a proper metric D : X x X --> R(>= 0) defined on X, we show that every block realization of D can be "embedded" canonically into the tight span T(D) of D and characterize the subsets of T(X) that can be obtained in that way as the "canonical image" of the vertex set of a block realization.
