1 tripod, 1 remote, 1 camera that it turns out can only do continuous shooting with self timer rather than remote. 1 chair for jumping off (turns out it tips over). 1 wooden box (lower, not enough height and had apparently rotted through over the Winter. Ow.) LOTS of jumping. Lots and lots.
And even then I only really managed to get my feet in, rather than a full SP. Plus full SP whilst jumping means it's impossible to pick a flattering angle. I think I need to start running or something.
