Re: Need help stitching my helicopter panorama!

Ed,
You should have mounted the camera on a monopod and hung it out of the
door so it was below the skids, using a remote release rotate the
monopod and take a bunch of shots while the pilot held the chopper in
a hover. No need to level since the camera is hanging. If you shoot
lots of frames fairly quickly you should get some that match for
stitching. If the camera is angled slightly down then you should only
have to stitch in a zenith of the sky or the underneath of the chopper.
Sorry you had a wasted trip.
