My first reaction is delight to see my two main interests in photography
combined so successfully--stereo imaging and immersive panoramas. I
really enjoyed the stereo effect, and was encourged to find that one
problem I had anticipated does not arise. I had thought that with a
fixed separation between the two lenses taking the L- & R-eye images
the stereo effect would deteriorate as one zoomed in and be exaggerated
as one zoomed out. My thinking was that you need more separation
between the lenses to generate the same sense of depth when you use
lenses with longer focal lengths--in conventional stereo photography,
that is. But I was pleased to see that the stereo effect remains
strong--and perfectly natural--even on zooming in to the equivalent
of a medium-tele lens. As a matter of interest, what lens separation
did you use?
While the second image is most noticeably affected by pigeons who
wouldn't sit still for you, I do notice problems with retouching in
the first and third, too. It's a rather strange effect, as if the
retouched image is flat, and not exactly in the plane or planes of
the surrounding images. Obviously a parallax problem.
It seems to me that some of the problems at least partially solved by
the PhotoShop CS3 ability to combine images and eliminate overlap,
and/or by the "smart" blending of images affected by parallax and/or
partial images of people moving between frames, should be amenable to
the same kinds of technique. Although from a rather different, er,
perspective, of course... <grin>
The problem may be to interes one of the extremely able people who
might be capable of this enough to get them to actually work on it.
This is one project I would be delighted to contribute to if it
were done as in Open Source, for instance. Alas that I have no
other specialized skills to contribute...
It would make an ideal Google project if someone as effective as
Yuval could catch the vision and provide the motive force to get
something done.
