I downloaded the demo of Photoscan Standard version first, and was able to stitch a spherical panorama, and the output preview looks pretty good, but of course, I can save from a demo. I then got the trial version of Pro, and the output is complete black. I doing the same exact process in both. Standard works, and Pro is all black.
A screenshot of the problem is attached. Standard on left, Pro on right.
Any ideas?
