Hey man, Sorry I didn't see this before...
They are brothers... they run a company called Nessen Forged... they sell those wheels. Which I been eyeing a set for my car.
I can answer the questions you asked....
I shoot with a 5D MkII and the lens? I think it was probably my 28-135mm Canon lens. These photos are not HDR but I did use various exposures to get the lighting right. I use Photoshop for my post-processing.
If you are interested... check out this page...
Before VS After
It shows the before straight out of the camera photo and after all the exposures are merged and post-processing is done.
