essential item often forgotten in aerial photography
used this Ken-Lab gyroscopic stabilizer doing aerial photography of
Uaxactun, Seibal, Nakum, Tikal, Yaxha, and Lake Peten Itza in the
1970's. The results were great. You can see the resulting aerial photographs
of the temple-pyramids of Tikal on our Web site.
Linhof Aerotronica 69 has a harness for suspending it but I am not
sure how to attach this when shooting "outside" the helicopter.
We use a Bell Jet Ranger helicopter, remove the back door, and sit
half outside the chopper. Our camera is thus normally also outside
the helicopter. We are (hopefully) held in with a safety belt, but
I would need to test the Linhof harness to see how it was fastened
if the photographer himself was partially outside. Even with a harness,
though, it would seem that the gyroscopic stabilizer would definitely
be needed, since the harness straps would transmit the vibrations
of the helicopter directly to the camera.
