I was attracted to this old truck with orange oxidized paint. I set up 4 flashes. One to the left of camera and another on the left side of the truck and another on the right side of the truck. I placed the 4th flash inside the cab and bounced it off of the ceiling. I took a test shot for the glow of Las Vegas in the distant and figured out that my exposure was 30 seconds @ 6.3. I then set my flashes accordingly. The flash inside the cab is on full power.
