@VMR - this was using what i called as areal-pod
I mounted my camera on the tripod and opened up all the legs and lifted it high on top of the gypsy so it sort of gave me a angle of view which would be higher than what you get on a elephant back also. Effectively this was around 15ft on top of the ground level. Triggering was done either using a remote trigger or self timer @ 10secs. One more from that experiment i had posted long back here >
