Re: Macro panoramas with webcam
- Oh wait, HORIZONTAL fov is 46 degrees, not vertical fov.
Silly me, that's a lot better of course!
More likely about four rows then, including zenith and nadir.

- 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.
