In all fairness, this lighting setup is not for a commercial. It’s a manufacturer’s demo display. But it graphically shows how cars reflect the sources lighting them. Maybe you want hot spots from the fresnels above. Probably not. A long gridcloth glowing from above would create a beautiful source for the cars below. Look at a car in the midday sun, and then compare the effect at magic hour, when the sky is aglow with (hopefully) glorious gradations of soft blue to orange. I think Bill Bennett, ASC and David Darby, ASC would agree.
