I've been playing with the layout branch, using a test project with
UW-footage [1]

Because this project was done with too little overlap between lines, i have
made separate projects for each line first, to see if there is enough
overlap anywhere to run it through Hugin, the three first lines are shown
here [2].

It is obvious that the low contrast, low overlap and uneven focus, because
of motion blur and wrong focus setting makes this a very challenging project
to use Hugin and automated CP detection on. On the other hand, the detail
resolution of the end result is not that important, it is the overview that
is the goal, so some misfit is ok.

I have a couple of questions:
1. I would like to merge the lines manually in a program like Gimp or
Photoshop as different layers.  Is it possible to get the negative space
(black) of these uncropped lines as transparent alpha channels straight out
of hugin?  Maybe this is what already happens in the output?

2. Some parts become more smeared than would be expected based on the
quality of the photos, see for example the mid section of this strip [3].
I recollect a discussion here that if the overlap of images are large, image
fusion would be done rather than seam blending. Is that so and is there a
way to prioritize seam blending?    In this case when the images are not
perfectly aligned, the fusion would just smear.

Cheers

hull.  Photographed with a NikonD300 and a 36mm eqv lens. (not wide enough
for this application!)
