Guys, Hans Nyberg infos help me out a lot ...
I borrowed a iMac DuoCore from a friend and using the settings proposed by Hans
The 12 images made with the 16mm fisheye stcichted automatically on PT MAC
On Ptgui I could NOT make it work ...
Now I have to try sticht the 18 images w/zoom 18-70mm
Any ideas on the settings Hans ???
I went to the marvelous fov calculator from Frank and all the infos
that it gave me showed up the same as on the auto - EXIF in PTMac ,
but I could NOT make the Optimize part ???
I can't figure out why...
It looks ok on the Panorama Editor, but if I try to Optimize it goes
completely wrong ?!?!?
Thanks to everybody and if someone or Hans could give me now
directions with the 18-70mm lens would be nice :-)
Sincerely
Ayrton

To big for Photovista probably. Depends on your computer.
And Photovista is not an exact stitcher.
It only use a standard logaritm for remapping. And no compensations
for horisontal differences.
It is like using PTMac or PTgui without optimizer and all values set
to zero.
