Talking of borecams there are very nice low level borescope pics (of
-- the viewpoint here is only a couple of millimeters from the ground
with some of the shots. It would be great to be able to have panoramas
from that viewpoint.
Borescopes can have a fov of up to 90 degrees or so. And that is a
circle, so it would be a challenge to shoot a spherical panorama with
one. But you can use a DSLR on one. And I think if you rotate the
borescope along its long axis the rotation is NPP.
Ive ordered another Logitech Quickcam Pro for Notebooks webcam -- and a
Sunex circular fisheye for the 1/4" format and I will see if I can
adapt the fisheye to the webcam -- shortly. The Sunex DSL216 should
give coverage on that webcam like a shaved Nikkor 10.5mm on fullframe
- Here is another kind of "orbit" webcam, also good for capturing panoramic views
... I've programmed it to look where I want pretty much
This movie is actually with my Logitech/Sunex webcam, being about the central 140 degrees of the fisheye view. The lighting is from the LED on the webcam -- a handy thing for closeup views, pity it is red.
