Before shooting, we are asked to gaze out a window at sunset in a room lit with tungsten light. After one minute, we look back into the room, then again back out the window to note the difference in lighting. What I noted is the outside light was blue, inside orange. The eyes quickly adjust to these changes as you move back and forth between light sources.
We were then to shoot a series of photos combining different types of light sources. The first set was shot about an hour before sunset and shows tungsten to have an orange cast, fluorescent blue-green.
