I've done a few shoots with guys and their motorcycles, and they are just so easy to light! One bare flash takes care of the person and the bike, with little or no extra light spillage.
My buddy Tom has a 1979 (I think) Yamaha. Old school bad ass.
We shot these in an underpass on the Boulder Trail system. Couldn't do that with a car! (although it would be great if I could).
I'm not sure which of the above 3 shots I like the best.
I was originally very fond of the middle one (with the PS filter), but now I don't know.
