Bad stitch of zenith

[Niklas]

Hi!

I use Canon EOS 5D with Canon EF 15 mm f/2.8 Fisheye on Nodal Ninja 5 L. When I stitch images in PTGui the stitch between the zenith image and the others are horrible. If i leave out the zenith image I get a good stitch.

Does anyone have suggestions on what I should change in order to get it right? I have tried at least ten times with the same result.

Best regards,

Niklas

Have you tried manually adding a bunch of control points to the Zenith shot? You can also set the "blend priority" of the zenith to something like "50" and see how that works for you.

Was the Zenith shot from the same tripod position, or did you move the tripod and shoot the Zenith? If you moved the tripod, then you'll need to use PTGui's "Viewpoint Correction" function (which has a good tutorial in PTGui's help section).

There's a PTGui user's group, too:

Thanks! There seem to be something with PTGui. When I ran the alignment several times it worked. I don't understand why, but think that I will be able to solve it. :-)
