NEF Thumbnails

[Graham Vickers]

I have just installed SP2 on my Windows XP machine.
All went well except for one problem.
I am now unable to view NEF files thumbnails in Windows Explorer. jpeg, tif,
bmp and gif files show thumbnails as before.
Any ideas.

Cheers
Graham

NEF files are RAW files from a Nikon camera. Explorer will not display
thumbnails for these files. Did you have thumbnails for these files, using
Explorer before SP2 unless they were something like .thm (or something like
this) files attached to the NEF files.

Sorry, didn't work.

Until installation of SP2, thumbnails for these files were shown in Windows
Explorer. The files were downloaded straight from the camera, so I don't
think there were any attachments. I could view them like any other picture
file.
With SP2, all I get is an icon

....in addition to the above, go to Nikon support and see if there is a
recent upgrade to the Nikon camera/viewer software and install it if
there is. Otherwise, open the existing Nikon camera/viewer software the
look for a setting to create thumbnails and re-check the option.

I am still on SP1 and checked a folder with some RAW files taken a few
months ago with a Minolta A1and not yet converted to JPG. The RAW extension
with Minolta is MRW. These is no thumbnails available for these RAW files.
Only an icon with the file name.
Since Explorer cannot read RAW files, I seriously doubt that you indeed had
thumbnails for your RAW (NEF) files. Maybe you were using Photoshop to
display thumbnails and now SP2 is interfering. If so let us know.

Definitely viewed in Windows Explorer.
I don't know if the Nikon View software installed a plug-in so it would show
thumbnails. Tried reinstalling Nikon View but didn't sort out fault.
Definitely a SP2 issue, both machines I use suffered the same problem

I had already updated Nikon View to the latest version.
I guess this is why I shouldn't install the latest stuff from Microsoft on
my machine ;-)

 

[Yves Alarie]

Interesting. Nikon must use a system different from Minolta with their RAW
files because Explorer has no capability for opening any kind of RAW file.
I would go to this site
http://www.dpreview.com/
and join and then post your problem on the Nikon forum and see what other
users have to say. At least you would get Nikon users.

Since MS has never supported camera RAW formats, I cannot see how an MS
update would change the ability to view thumbnails since that ability is
proprietary to the camera software which provides a jpg rendition of the
RAW format photo so that explorer can "see" it. The problem must reside
in the Nikon software setting that permits the creation of the RAW
thumbnail, and is usually a checkbox in the settings for the program.
Perhaps removing and reinstalling the Nikon software will correct the
problem.

I have the same problem, I don't know if it was Nikon capture or Nikon View
but I could see NEF file thumbnails in Explorer. SP2 killed the thumbnails.
I completely reloaded XP and SP2 clean and then loaded Nikon Capture and
Nikon View but the thumbnail views are still not working.

I can confirm that NEF files used to preview fine in Explorer, but SP2 broke
that. Hoping to find a fix, but alas not here yet at least.

Removing and reinstsalling Nikon software does not fix the problem. There is
no checkbox mysteriously unchecked either. A NEF file is similar in format to
a TIFF file with the preview image embedded in the header. SP2 just refuses
to show it. MS, if you read this, please post a fix for this!

Hello,

update would change the ability to view thumbnails since that ability is

That's not true.

In Nikons RAW file there is a JPEG or TIFF thumbnail (depending on
compressed or uncompressed NEF) embedded in the images exif header, size
120x160.
Just changing the file ending to jpg instead of nef does show this
thumbnail (even with SP2). There is no need for any Nikon software to be
installed. For supporting NEF only this registry entry wass needed:

[HKEY_CLASSES_ROOT\.nef]
"PerceivedType"="image"

By that Windows "knows" that it is an image files and provided thumbnails
in Explorer.
Unfortunately something has been changed with SP2 by Microsoft, it won't
work anymore.
Obviously only known file types (=extensions) are now supported (allowed?)
to use the thubnail preview ability.
