Re: My first cilindrical panoramas

Thanks for your comments, and specially thanks Pat for your explanations.
Since the firsts panoramas I send you, I have been reading several
messages at this list and other resources in the web to learn a little
more. It is really amazing the learning possibilities that the web with
people like you offers to the begginers.
I have used several ways to shot the nadir, allways thinking in large
expositions. I think that may be much work, but a way that I have find
usefull is shooting 3 shots to build the nadir: 2 of them with the NN
mounted, looking at floor and rotate 180?, and the third one using Hans'
method http://www.panoramas.dk/quicktime/qtvr/nadir.html
<http://www.panoramas.dk/quicktime/qtvr/nadir.html>
I save the first two as a tif, erasing the tripod, and paste a portion
of the third one in one of the two firsts to replace the empty space.
I found that shooting only one nadir taking the tripod away increase the
parallax error possibilities.. And the postprocessing work to correct it
was too hard, especially when you have an object very close.
I have upload two examples here:
- http://www.vincles.net/360/nens_passera_rem.html
- http://www.vincles.net/360/porqueres3.html
In porqueres3.html, 3 shots of each one, mixed using Photomatix: f13
10s / 5s / 20 s at 320 ASA
In both cases, the nadir shot without tripod contains parallax errors to
heavy to me to correct. Using 3 shots, the space to fill is so little
that blending is easier.
In any case, i'm expermenting.. I don't know if it is a recomendable
method.. what do you think.. ?
I hope to repeat the first ones, the lake at night, very soon and show
them to you.
Thanks a lot! :-)
