Warning, this video may give you a little bit of vertigo. Stijn Van Hulle posted this BTS video of him photographing rock climbers in Freyr, Belgium. The images were shot to compliment a new guidebook for Freyr - "the most important climbing area in Belgium." It's a harrowing job to be sure, but the payoff is breathtaking - a gorgeous landscape overlooking a castle that dates back to 1378.
Particularly interesting is his rig for getting that extra distance off the slide of the cliff. Ladders are most commonly used, but Stijn's A-frame rig seems to get the job done with a bit more stability. In the beginning of the video, he says he is setting out to "capture the sensations of rock climbing in a single image." I'd say he's come close enough for me.
