Thanks for the link
I read through most of the article and it seems like the author just says the same thing over and over again (use fill flash).
Not that that is bad advice, but there are a lot of other details that deserve attention. Composition, use of polarizing filters to eliminate reflections, small details like turning the cars wheels so that the camera sees the face of the wheel and not the tread of the tires...
Some of these were mentioned briefly.
It seemed like the target audience was intended to be people trying to sell a car and not necessarily those wanting to take the most striking photos of one.
Still worth a read, though.
Thanks, again.
