D800 real world images. Did Dpreview wipe the ISO on purpose in this image?

Some of the images look good. Noise, IMO, is pretty well-controlled.
At 1600 ISO, you see colour speckling you don't see with cameras like
the D3s, but this has 3x the pixel count.
But, the image below for some reason has no ISO indication that I can
see. I'd guess it's about 6400.

Nikon doesn't follow the "rules" for EXIF very well. They use "other areas" to
append data in some way. On some of my Nikons, (mostly the D90), and in some of
my software, the EXIF doesn't show the ISO if I set it to the higher numbers.
Some software is better at finding it than others. If I really want to know the
EXIF I use Nikon View to see it.

The following is an Exif copied to clipboard by Irfanview... no ISO is shown, it
was 6400. (scroll down for another example)

Appropriate software doesn't seem to have any problem.
Phil Harvey's /exiftool/ is probably the premier Exif
display tool.
