Thought I'd throw this out here.
Did this a few weeks ago on location at an old miltary fort. Its actually a pillbox/bunker that is almost completely buried under sand at this time, but there remains an obscure path to both entrances, one of which can be seen behind me.
I had a couple of Canon 580 EXll strobes. One shooting through a small softbox to light subject and another off in the back shooting through a red gel to the wall in back of me.
A vivtar 285HV shooting from the back to light side of subject and hair.
It was good fun till the wild dogs decided to come strolling through. . .
