+\section{Alternative Views of Overlay Modes}%
+\label{sec:altviews}
+
+An alternative set of source videos used to provide a different real world view is shown here to help illustrate alpha blending. They use a landscape photo as one and the other is half of a color and half of a black and white gradient photo. First is shown the Aritmetic, Logical, and Graphic-Art views.
+After that the Porter Duff overlays are shown using the same source videos but
+with each of the Source videos offset in a different direction so that the
+generated output is more obvious.
