I’ve been toying with the idea of rig shots for the past year or so, and finally got around to attempting them. This was fairly “rigged” up in a bad sort of way, but I’m happy with how the photo turned out for my first attempt. Other than brightening the image up there was no photoshop involved.
Full car motion shots coming soon 
I’m pretty sure I have something stable and light enough worked out where I can attach it to virtually any car in under an hour without any damage/screwing/bolting etc to the chassis. I’ll be building that in the next few weeks.
