Help - Why am I still having troubles with my panos?
Shooting on a Canon 10D body, with a Canon 15mm fullframe fisheye.
I usually shoot 2 rows around of 10 shots at plus & minus 30 degrees,
plus a zenith and nadir shot. I have a panohead that is based on the
Manfrotto spherical VR head.
Problem - some horizontal (or near-horizontal) straight lines in the
pano - such as roadways - do not stitch with smooth transitions
between frames in the pano, particularly when the line is relatively
near the horizon - they seem to be still straight lines where
stitching between frames is obvious, with no morphing. This seems to
occur near the horizontal joins at the horizon of the pano.
I use Helmut Dersch's Panotools running behind PTGUI 5.8.4, I now
shoot in RAW with the orientation tag set by the camera off and I
convert in Photoshop CS2 to TIFFs; I set the stitching points
manually; ! use Enblend where the light changes to soften the
transitions as needed.
In PTGUI is straighten the horizon if this is needed, and patch a
zenith and nadir as necessary.
The QTVR is created with Panocube's registered version.

off the preparation server), URL

rs.html - look for the roadways. I can post this pano to my home
space if you want to see it early - let me know.
I am not looking for answers such as "switch to a circular
fisheye", "buy another camera" type-reponses. I suppose what I really
need to know how to set up PTGUI to stitch these properly.
And while I am asking questions, I need info on using layers to paint
in or out elements at frame transitions - the info on the PTGUI FAQ
about this doesn't seem to work in CS2 even though i follow the
guidance exactly.
What am I doing wrong? Any help will be most appreciated.
