What camera/format are you using?. How much light are available there?.(posted 9042 days ago)When we shoot car sequences, we always keep the background as it is, mainly because we have no money to lit it all. But you have to keep your subjects lit. Try using a pair of lights from the bottom of the car aiming your subject's face with 45 degrees. Using pale blue or blue gels could be fine, depending on the scene itself, the moon. the weaher, etc.
