No, just use multiple pairs of horizontal control points. You

Yeah, isn't it! I pulled it off the hugin flickriver stream.
Ok, I have an HDR EXR image that was successfully and completely

The horizon should end up going through the center of the pano.
The pano can then be cropped to show just the image.
That is what I did ... I guess because the picture was literally

I found vertical lines work better than straight lines which happen to

be oriented by overlapping normal control points, imo.
I should probably start a new thread for this, but whatever...
Hugin HDR panorama output (2010.4.0) is broken. Whether outputting the

format. For example, ProjectName_stack_hdr_[[:digit:]]{4}.exr. These

Mm sorry FOV ranges from 142 degrees horizontal to 144 degrees
vertical according to the sticther tab... whereas I calculated FOV
from the images tab as (yaw group0 - yaw group1) * (# groups) +
[2-(mod2 #groups)/2](yaw group1 - yaw group1). What is the difference

Thanks for all the points, I've aligned specific stacks and created
stack masks, now despite a mundane landscape the fused version
nonetheless looks impressive.
My panorama is outputting to exposure fused from stacks as TIFF and
HDR as EXR, in both cases the blend process has taken about two

I ran a rough test (I don't have the tripod) and determined that my
NPP was displaced by approximately 10cm - which caused about a 4px
pixel error for mid-range objects. It's really neat that object
distance can be estimated from pixel error.
I've noticed that enblend is 99% of the stiching

thanks for the suggestions:
Just to be clear, the problem is not in my control points. I have 24
stacks with 50% overlap, per overlap I've manually placed 20-40
high-correlation well-distributed accurate control points. After
optimizing my average error is 0.4, rms error 0.6, max error 1.7.

Important: Horizontal, vertical, and straight lines are evaluated on their
output projection.
Hm, so that's why my mercator projection + straight line @ ~25° was
throwing off the alignment...
so this means that:
equirectangular: vertical lines only, plus horizon line
