Low contrast and saturation after enblend [3 Attachments]

PanoTools NG mailing list
I have been using Hugin for a few years now, and for the most part love it
and have done some neat things with it. But after downloading the last
version (2014.0.0.5da69bc383dd), I have experienced a problem: when I
stitch my images together, the contrast and saturation of the resulting
panorama is much lower than the original images. This seems to occur during
the enblend stage. That is, I see my remapped images being created, and
they look fine. But the final panorama looks faded (low contrast and
saturation). What am I doing wrong?  I don't think this was ever a problem
with the older Hugin versions I was using.

I am attaching three files. One is the panorama, one is one of the remapped
images, and one is the pto file. (The JPGs were originally written as TIF,
but to get them small, I converted them later. Also, this example is
incomplete, I have the nadir image and material to get rid of the tripod
shadow, but haven't stitched it yet.)

These are being stitched as LDR, although I have stacks with other
exposures. The other exposures are turned off in the previewer, so I would
think that they are ignored.

Any help anyone can give would be much appreciated!

Thanks, Thom

Hi,I had the same problem with the new version also.
Quick fix... Purchase a license for PTgui.

tmodes proposed the following answer:
This is caused by a bug inside littlecms2 used by enblend. Add the parameter --no-ciecam to the enblend command line parameters.
Or recompile enblend with littlecms 2.5, where the bug is fixed.
