Public bug reported:
This bug is 100% reproducible.
- Expected behaviour
Using F-Spot to open a NEF file, the correct 10 MPixels picture taken
with a Nikon D60 is shown.
- Observed behaviour
If the NEF file has been edited with TransferNX, a small 320x214
thumbnail is shown
[More details]
NEF files are raw data files created by Nikon dSLR cameras, and other
than the image data (sensor, white balance, colour profile,...) there is
also an embedded jpg that acts as a preview. This jpg is full resolution
and has a quality of about 85~90. Being processed exactly as specified
by the camera settings, this jpg is used by several programs to display
NEF files. Opening a NEF file in Ubuntu defaults to F-Spot, and works OK
in Jaunty and Intrepid.
Once a NEF file (Nikon RAW file) has been "developed" with any Nikon
software, the thumbnail is updated with a high quality jpg to reflect
the changes made (white balance, exposure, lateral chromatic
aberration,...). F-Spot opens successfully NEF files edited with
CaptureNX 2 (the $180 retouching package sold by Nikon). However, if a
file is edited with the freeware TransferNX, F-Spot no longer displays
the correct thumbnail. On the other hand, a 320x214 thumbnail is shown.
Furthermore, the colours are all off, although GQview is able to display
the colours OK. It must be noted that the full thumbnail is still there,
since dcraw is still able to extract the full resolution jpg.
I have tested this only with NEF files created with a Nikon D60 and with
TransferNX 1.3 and 1.4 running on Windows (there is a Mac OS X version).
I can provide two sample NEF files (original and edited), but one file
is about 10 Mb.
