Here are three structures.  For the last one I chose the darkest of three exposures for the way that the darks massed into silhouette and framed the hotter lit areas. Simplifying the darks turned the eye and subject onto the heat of the light. Once I saw it like that it suggested a painting possibility, simplified and dramatized. I don't think about using such strong contrasts normally, so this awakened me to a neglected avenue in the studio. We'll see.
