I did not see the origional question posted asking about
the `panorama head', but would like to pass along some
information I learned from someone who does aerial photography.
The overlap he uses is 40% on all shots. This corrects for
any distortion that may be caused by any lens. I have done
some panoramic shooting and find that if you make a mental
note of a tree (or something) in the far right side of the
frame, then move the camera so that it is in the far left,
when you get the prints back, they don't match. But the 40%
idea will componsate for this. Locate the tree off center on
the right, then off center on the left to get your 40%. Use
a tripod for sure.
It uses up a lot more film and paper, but depending on what
you are trying to achieve, will provide the most professional
results.
The photographer I learned this from, Bill Woodcock,
in Miles City, Montana (yes you can see the end of the world
from there) uses a black and white film called H&W Control.
This film provides vertually grainless prints. He uses a
Hassablad 2 1/4 instead of the usual 8x10 format for his work.
The prints he generates are anywhere from 8x10 to 24x30 depending
on the results needed for the job. With either size he gets
no grain! The film is that good.
