The original tiff from the above link was made using a custom camera
profile which produced some oddly oversaturated blues. In the
above-linked zip file, I replaced the original tiff with a tiff made
using pfstools, dcraw, and the dcraw default matrix profile.

The replacement tiff still has an alpha channel and also an embedded
thumbnail. So the zip file also includes a second smaller version
without an alpha channel and also without a thumbnail.
If you'd like variations such as compressed tiff, 16-bit floating point
tiff, etc, let me know.

GIMP 2.8 probably never will be able to load floating point tiffs. Here
are links to screenshots of high bit depth GIMP 2.9.3 from git and
darktable 2.0.0, both displaying the floating point tiff:
