Me doing a backflip.
To take this photo I set the camera to self timer and ran to the trampoline, waited until the 'pips' went fast and bounced one more time, then did the back flip, then jumped off and went out of shot whilst the camera finished the shot! Camera & settings were:
Canon 400D
Canon 50mm 1.8
Velbon Tripod
Nissin flash gun
Aperture 3.2
30 second exposure
ISO 400
