(I have not tested yet the new panostart, but I followed your workflow
published with the prior version, which I assume is just more automated
now.)

For handheld exposure-bracketed spherical panoramas, I sometimes find it
quite difficult to correctly optimise the position/distortion/etc. of
all of the images at _once_ in hugin (i.e. the individual exposure
variants within a stack and then the partially overlapping images/slices
creating the panorama).

For non-bracketed handheld panoramas, I first optimise for position,
lens distortion (b) and view (v), then I create a new lens for each
panorama slice and optimise only for position and shift (d, e) to
correct for camera movement between shots.

Application of the same approach to bracketed handheld panoramas does
not lead to good results, since I am trying to optimise two different
sets (the images within a stack and the partially overlapping stacks
with each other) at once.

So I find it easier to use align_image_stack to output remapped stack
images, enfuse to merge them to a single image and then create panorama
only from the enfused images in hugin using the approach above.

Of course, the problem is paralax error due to the camera movement
between the shots, I should probably practise more with the philopod and
have a firm hand...

Do you have or anyone else have similar experience?
