Cd,22-degrees( as per W.A.Mair's research findings ) is the largest angle on the trailer.
The Japanese Automotive Research Institute(JARI) uses a telecamera,at 100 meters from a vehicle for frontal area measurements.MIRA,in the UK uses a similar strategy.
One might presume that their 'factory' photos are obtained this way.This would help compensate for optical distortion of an image.
I was only shooting from about 36-feet above the rig with a 'normal' lens.It's apt to guarantee a distorted view.
