Title:
  When HDR merging bracketed photos, EXR appears white in most apps

Status in Hugin - Panorama Tools GUI:
  Expired

Bug description:
  I've been struggling with this for a few days now, and finally decided
  to log a bug. I'm attempting to merge together three JPG's taken with
  my Nikon D5000 using bracketed exposure values. I found some tips and
  instructions on merging into a single HDR, and I think I have the
  process correct. I was using the 2010.2 version initially, but since
  upgraded to the latest dev beta, 2010.4 beta 2. The stitching page
  looks a bit better, but the results are the same.

  My process:
  1. Load images
  2. Set control points
  3.Optimize only position / view (the default "wizard" settings mess up the alignment)
  4. Optimize FOV / crop
  5. Generate "High Dynamic Range Merged Stacks"

  So.. I also have the latest Luminance HDR 2.0.2 as well as Photoshop
  CS4 with the latest available EXR plugin. I also have Piturenaut 3.0
  for HDR processing. When I open either the intermediate or the final
  stacked HDR file that was generated with Hugin, the entire thing
  appears all white in Photoshop. When I attempt to open it with
  Luminance HDR, it crashes Luminance.

  Fortunately, I found that I can open the generated EXR in Picturenaut
  and then re-save the EXR from there to process it with Luminance. This
  is an annoying workaround, but at least it works!

  I suspect this is a bug in hdr_merge... possibly to do with the EXR
  libraries..

  Best regards,
  -Sean

  PS. If you would like a copy of the photos I'm merging, let me know
  the best way to send them over.
