The links claim to be jpg files, but they point to bitmap files, which
is odd.

And they are the worst examples of "test photos" I've ever seen...they
do not do any DSLR justice, nevermind the D80 or A100.

Clear out your cache.
The jpg listed above is indeed a jpg.

    Is it possible that the server is looking at the browser's
signatures, and if it sees IE, it serves up a converted BMP instead of
the original JPEG?  A crazy thing to do, given the extra download time
needed for the BMP, and the additional resources needed at the server
end to run the conversion.

    But with Opera as a browser on Sun's Solaris OS and UltraSPARC
hardware, I get nothing but JPEGs.

    Perhaps your browser is locally converting to BMP for whatever
strange reasons may lurk at the bottom of Microsoft's hard hard heart?
That might take almost as long as downloading the full thing in BMP from
the server?  After all -- BMP is the native image format of Windows
machines, so it may be necessary to convert it to display on such a
machine -- and for whatever reason, it decides to save it as BMP instead
of the original JPEG.

    Enjoy,
        DoN.

    Bingo!  Just as I suggested in another branch of this thread --
except that there is at least a fix posted.

    Good Luck,

I read that...I only have two objects (Flash and Java) which report as
being installed fine, and removing them doesn't make any difference.

>    Bingo!  Just as I suggested in another branch of this thread --

I would believe it was a damaged activex object or other file on my end
if it happened on any other site, which it does not. I've downloaded
from thousands of pages and never experienced this problem.

However, I think I narrowed the problem down to the lack of the Japanese
character set on my computer.

Because I don't install language packs, IE is defaulting to bitmap when
the image file is being displayed inside of IE. But if I bypass the
display and download directly to my drive, the file is stored correctly.

The funny thing is, if I go to numerous other Japanese sites, files are
displayed as jpg just fine. It's only this one site that does it.

Weird...but I'm not going to worry about it anymore. It's working fine
everywhere else.

Amazing! Images taken with a camera that has not even been released
yet! (And it is not scheduled for release for another month.)

Maybe you would like to see the terrible color balance, noise, and
purple fringing in my test shots with the Canon 1DS Mark III? Or the
Hasselblad 1D-82? Or any other non-existent camera.

Pre-production samples have been in the hands of select people for a
while. Where do you think sample photos for Nikon brochures, and online
tests get their info?

And you honestly think that these photographs were produced by some of
these "select people?"

If these photographs were taken with a D80, lets see some proof.

I didn't say that. I merely stated that pre-production samples have been
in the hands of some people for a while.

Download the pdf brochure for some interesting details.

If there were taken with a D80, they suck. I'm confident the images are
not representative of the capabilities of either camera, real or not.

The pixels are 1/3 smaller than the D50.  No surprise if there is more
noticeable noise
at 1600 ISO.

Well yes and no.

I went back and checked - if you click on the thumbnail it takes you to
a bitmap file. The first sky scene is a 28.7meg file.

But if you right-click on the thumbnail and save the target image, it's
a jpg...very weird behaviour.

I have both here and I've compared them - they're the same image, just
two different formats.

    Including the same resolution?  (Obviously not the same size,
given how poor BMP is at compressing -- that is, it doesn't. :-)

    I'm not even sure that my system could *display* a BMP image
with my browser, since BMP is native to Windows, not to unix.  I do
have programs which can render the images, but as I said, I'm not sure
about the browser (Opera, FWIW.)

    The first image I just downloaded directly using "wget" (no
browser involved).  The second one (the one with a tower in a gridwork
as the central part) I clicked on the thumbnail, then selected to save
the resulting image to my system to check -- and both of those were
JPEGs, and both with full exif data.  I don't *think* that my browser
would download a BMP and convert it to JPEG -- and miraculously preserve
the exif data, which I don't think can even be included in a BMP image.
:-)

    Enjoy,
        DoN.

Same resolution and pixels...but as I said above, it's a 28.7meg file.
It takes about 3x as long to download over the same jpg.

See my next post...

Are you using IE? If so, it's likely your temporary internet folder is
full. Just clear it and the correct .jpg suffix will return. Or use a
better browser, Firefox.

I'm using IE, but the folders are not full because it clears them when I
close IE.

It's not a browser issue.

The files were downloaded to my harddrive. The files are different size
and coding. Like I said above, I have the two files here, one is
definitely a bitmap, and one is a jpg (hex editor to check).

Not a big deal really...the source code on the webpage shows they're
doing it right from what I can see, but it's probably a proxy caching
issue on their server.

however.

I don't know why you can't read exif - seems to be intact.  Of course
there is no "proof" it isn't forged.
The D80 / a100 comparisons aren't particularly interesting due to the
large difference in exposure, and unless you can read japanese on the
other link, no idea what NR settings were used in camera etc.

Exactly. Anyone can change EXIF data.

1) There are no D80s in the hands of the general public.

2) None of the credible reviewers seem to have a D80 yet.

3) Anyone publishing pictures like that could pretty well be guaranteed
to never be allowed near a preview copy of a new Nikon again.

4) The pictures have been processed, as noted by others, so even if
they were taken with a D80 we have no idea what was done to them in the
interim or what the settings were.

Without further evidence that these photographs are genuine and
untampered with they should be simply dismissed out of hand.

To be sure.  However I would expect that the EXIF be intact in the
presented image.  It is not (at least as far as PS E 3 can tell.  Forged
or otherwise (there is a risk to "forging" as well as one might put in a
giveaway that it is a forgery).

Yep.

Cheers,

I DL'd the photo as shown and loaded into PS Elements.  All EXIF fields
were blank.  That may be a shortcoming of PS Elements, OTOH, I DL files
from elsewhere and the EXIF are intact.  That was not the case with this
image at the link provided.

I thought the D80 shot is brighter and indeed, it's shot at 1/20sec and
the A100 shot is 1/40sec. The test is invalid and as they have the same
sensor, the result should not be that drastically different.

Regardless of the validity of the image having come from a D80, I'm surprised
that no one has commented on the UFO's that appear in the sky area.

BTW most of the EXIF data shows up in the JPG image (downloaded with IE) and
opened in PS CS2.

I thought it was odd at first too, then I realized that it's not a real
sky at all - it looks like an artificial sky painted on the canopy or
roof over the area.

Yes, it looked like someone painted some of the covered entree plates, you
know the ones with the hole in the center, that the waitstaff all lift in
unison, when being served at a fine-dining restaurant. Heck, I though I had a
scoop for FOX News - oh well.

It is indeed a fake sky.  It is the basement of the Shin Yokohama
Ramen Museum in Yokohama City in Japan.  I've been there a few times
ten years ago.  That area was pretty dark.
