When opening the attached .exr image (created by hugin) I get an error. With 2.3.0 it throws std::out_of_range; with git HEAD it fails an assertion. It looks like they\'re both suffering problems in pfstmo_durand02. I\'ll provide process output for the two cases if I can figure out how to add more attachments.
I started with a much larger image than this, but I\'ve cropped it down to something reasonably-sized.
It\'s possible that the image file is malformed -- I\'ve certainly had problems with hugin_hdrmerge output in the past -- but in any case luminance ought to respond better than it does.
