Thank you folks for the positive reply !!!
That's not a trick, it's a normal work flow for a photographer/panographer ...
but to do this from a tandem parachute it's a total adrenaline rush ;-)
I used for this shoot a normal Canon 400D D-SLR with a Sigma 8mm/F3,5 lens on
a special homemade bracket (nodalpointadapter) and a normal monopod.
Also I used a cable release and lot's of tape.
Here are some making of pictures from this jump:

Have fun ;-)
