Abe,

This file reads just fine in OpenEV.  The default constrast stretch in
OpenEV is suboptimal but that is easily corrected by manually selecting
a stretch range.

There is no evidence I can see that libtiff has problems with this
image.  But I would not be surprised that many applications do different
things to convert this to a displayed image.  The TIFF file itself
does not force a particular display approach.

Best regards,
