problems with Nikon Coolscan 4000 .nef file


i actually try to load a RAW file created by the Nikon Coolscan 4000 Scanner.
Its a .nef file, original resolution 5408x3571 px, but i receive a wrong resultion and no image data.

Is it possible, that the Nikon Coolscan 4000 Raw files are not supported? (.nef is supported, but maybe the coolscan 4000 files are somehow special)

Thanks for your time,



Coolscan 4000 is not in the

Coolscan 4000 is not in the list of supported cameras :)

Generally, files from Scanners should be 3-component, not bayer-pattern. So, camera-targeted NEF-handling code will not work with scanner files because only one per-pixel component is expected.

BTW, if you provide any sample of Coolscan .NEF output, it will be analyzed in depth. May be, it is easy to add support for these files to LibRaw

Thanks for file. Downloaded

Thanks for file. Downloaded it, you may remove the file from Dropbox.

The list of supported cameras is updated very frequently, so no list on website. There is API call LibRaw::cameraList().
