Re: parameters for Nikon 995 in PTMac and Defish

I am trying learn to use PTMac and Defish.  Honestly, sometimes I am
just mystified by the parameters I should use.  I am trying to learn to
make panos using full-frame fisheyes with either of two approaches:
using PTMac or defishing them with Defish to stitch using QTVRAS.  I am
using six horizontal shots in FE2 mode.  Is there anyone out there who
would share their choice of setting for these programs with me?  They
really are not what I would guess, especially in Defish.  Particularly,
I do not know what the FOV (vertical and horizontal) when shooting a
FFFE in portrait mode (i.e. with the picture "tall" to capture the
highest amount vertically.)  Any help or pointing to tutorials would be
appreciated.  I asked part of this question before and someone guided
me on FOV, but I think they assumed I was shooting landscape.

Set the Fisheye FOV. If you can take a picture with the round fisheye, you can get an idea about the center.


I think that I'm going to talk about it at the IQTVRA summit in D.C. in a bit more than a week.
