Title:
White pixels at 180 wrap and zenith for 16/32bit HDR Pano
Status in Enblend:
Fix Committed
Status in Hugin - Panorama Tools GUI:
Invalid
Bug description:
When stitching my final pano for an HDR workflow I get a column of
blank/white pixels near the equator at the 180 wrap and an entire row
of blank/white pixels at the top. Here's the basic pieces of my
workflow:
- Multiple exposures at 7 angles with samyang 8mm + pano head
- Combined exposures to 7 HDR images using pfstools (sometimes exr files for
16bpp, other times tiff for 32bpp)
- Use hugin to: mask out pano head arm, find control points, optimize
positions, barrel and view and set output options
- Stitch with a script using nona+enblend to equirec HDR image
Can view example of the white pixels here:
- you're facing the 180 wrap when it first comes up
- zoom in at zenith to see the missing top pixel

When I look at intermediate files I'm pretty sure it is enblend that is the
source of the problem. I've tried several different versions:
- The stock version from the OSX binary on the source forge web site (v 4.1.1)
- Enblend 4.1.2_2 compiled with macports
- Enblend 4.1.3 compiled with macports (using my own updated portfile to grab
the 4.1.3 tar ball)
All three versions show the same problem. I'll attach a screenshot
pointing out the truant pixels as well as a minimal .pto file and the
script I use for stitching.
