Windy Night

Vantage, Washington, USA
Canon EOS 5D Mark III | ISO 200 | 32mm | 243 sec | F/4

From last night on the Wild Horse Wind & Solar Facility in Vantage. The conditions were challenging for star photography with a full supermoon and a cloudy sky. We experimented for a few hours with both short and long exposures. In the end, long exposures which highlighted the bright streaking clouds won out.

The final image is a composite of 3 frames: a low-ISO long exposure (4 min) for the majority of the scene, a high-ISO short exposure (0.3 sec) to capture the spinning blades of the wind mill, and a final exposure that shows Nate manually lighting up the wind mill for scale.
