i was wondering if its ever been attempted in a ski film or edit. onto a down rail specifically.
if so, or if anyone has experiance with the shot, please comment +K. ive done the shot in class but never with my own rig let alone on snow or on the mountain. i think it would be insane if done correctly shooting a down rail or other features thoughts?
