Cheers fellas.
Yeah, you photoshop the rig out. So for those less familiar with it, there's a 6ft pole hanging from the cars bodywork and the camera is on one end. After the photo is taken, you remove the pole and any reflections, etc with some photo editing software.
Not easy!!! (well, I didn't think so...)
I'll be ordering my own rig soon, so I'll be able to do more stuff like this - it's quite effective.
