Re: [PanoToolsNG] Black\alpha area around a panorama (hugin)
- I have not used Hugin but it looks like the vertical field of view is
set to 360 deg when it should only be 180 deg. The horizon is half way
between the middle where it should be and the bottom. Change to out put

says 127x94. The odd thing is that the horizon is in the wrong place
yet apparently straight. If the output image was repositioned to bring
the horizon to where it should be, at the centre of the output area, it
would develop a pronounced curve. I think the likely explanation is
that the vertical shift parameter "e" has been optimized to a silly
value. If so, resetting it to 0 and running optimize with e unchecked
should solve the problem.

said. There was no change in the preview though. You are correct about
the image being bend when the cross-hair is placed in the center of
the image on the horizon. I shoot the panoramas from hand or from a
normal, simple tripod (so yes, there are some parallax problems).

Try again resetting the pitch of the anchor image to zero.
- Marcel, It doesn't seem likely that we shall solve this problem without
seeing the Hugin project file. If you care to paste a copy of the
project file into an email to me then I would be happy to investigate.
The images would not be necessary.
