Mixing daylight and tungsten light

We were doing some photos with a hand model in the studio this week. For this scene of a glass globe in the model's hand I used a single tungsten light from the right mixed with natural daylight from the window on the left. Later in Adobe Camera Raw I enhanced the colors to increase the contrast between the blue daylight and the yellow tungsten. I also darkened the left side considerably to achieve the day-into-night effect.

The photo was taken with a Nikon D750 and Nikon 85mm tilt/shift macro lens. I like using a tilt/shift lens for close-up work because it allows me to control the focus areas by tilting the lens instead of having to close down the aperture too much.
