Let There Be Light, Part 3 (Mixed Lighting)

The intent of this challenge is to explore the complexities of light and color temperatures, and how our delicate sensors interpret them. This challenge is not for the faint of heart. It will require a working knowledge of light and how our machines were designed to react to it. It requires that we abandon our Auto-White Balance and select a white-balance camera setting manually. (As we remember, when exposed to a film's "emulsion", un-filtered light chose its own path of rendition. We were forced to anticipate, modify, or even craft our eventual result.) What I'm hoping to see in this challenge are deliberately crafted, in-camera images...where two or more different light sources are utilized or applied within the same frame to achieve a desired result.
