Exposure Bases Revisited [Discussion]

The focus of this paper is on some fairly difficult and sophisticated concepts that may not become obvious to the reader upon an initial reading. One key concept is that of "true exposure" as presented by Bouska, and its proxy provided by an exposure base. There are no complicated formulae presented in the paper, yet Bouska's observations that the subject is indeed complicated and intricate were realized during the discussions at the CAS Annual Meeting concurrent session were this paper was presented.
