This probably an FAQ, but I couldn't find an answer: when do you sharpen
spherical panoramas? Before compositing (i.e. sharpen the original images)
or afterwards, and if so, using what type of projection (I need to output
equirectangular in the end)?

Right! It looks to me that the remapping takes the average of two
surrounding pixels, on average.
i.e. with an image that COULD map 1 to 1, every source pixel
Thanks for your reply, Carlos.
Aligning the resulting equirectangular projections is an option, but I was
hoping to avoid having to filter the images twice, so as to keep the most
sharpness.

I was hoping to find a way to do it within the stitching process, to avoid
loosing any quality by double-processing the source

Though the loss of data from remapping a second time is negligible, so
I wouldn't worry about this very much.
I share this opinion.
Another option (besides stitch all toguether as Bruno said) is to use the
equirectangular just to align the
This looks similar to an older bug with the masking code. Can you
send the .pto project so we can confirm it? (no need to send the
photos).
It's not related to the masking code. The issue with the posted
project is the use of the translation parameters. If the images go
over the 180°

I'm seeing a similar problem in 2012.0.0RC1 (2012.0.0.0fc00635e11f built
by Matthew Petroff). I'm attaching the project file.
Same issue here. Your nadir image has non-zero translation parameters.
Set the translation parameters for the nadir image to 0.

Thomas, can you clarify what you mean by go over the 180 degree border?
Do you mean that I have a panorama that covers more than 180 degrees in
some direction? Or that some images cross the nadir or the zenith point? Is
there some explanation of what the limitation of the currently chosen
With any image processing it is always recommended that sharpening is the last
thing you do. Any adjustments after that affect the perception of sharpness
that the eye sees.
