I work as a Land Rover Experience driving instructor at the Carmel, CA school. The Range Rover Evoque was light painted for about 20 seconds during the 20 minute exposure with my iPhone's flashlight. The following morning I made another image to use on the certificates that are handed out after each lesson.
The tires are a little distorted from the wide FOV, but was the only way to capture the vehicle and sky in the frame.
