This is up for comments about how to eliminate vignetting (?)
Reducing the aperture, as mrpiv suggested, should
help. You could also increase the overlap.
Typically the Gigapan Imager shoots with 30%-40%
overlap. If you do "Gigapan Setup" you
could reduce the field of view and thereby get
overlap of 50% or more. That would help, also. The
disadvantage is that you'll shoot more
pictures to capture the same panorama, however.
Forest, First thing I noticed was that you shot at
f/4.3 on this pano. Vignetting will be reduced
significantly by shooting at f/8, which I believe
is the maximum available on the SX120. I noticed
you had used f/8 on some of your previous panos
with an SX110 with no vignetting problems.
Hopefully you have the opportunity to re-shoot.
But since you have already shot this, you may be
able to reduce the vignetting effects a bit by
selecting the option to use a larger blending
region and re-stitch. I am currently using an
SX110 which only differs in Mpx, 9.1 vs. 10
compared to the SX120 and I get good results and
always try to shoot f/8. Previously I had used an
SD400 which had vignetting problems even at f/10.
