Non-RAW NEF support
Locked
 
|
Hi, I don't know if it can be made in Digikam or it's depend of other
component but I would like to suggest to take in charge a special kind of NEF files. In fact, NEF files are most of the time RAW files out of the camera embed in a NEF container, including parameters used to develop the RAW data. But with CaptureNX, you can edit the NEF files to modify and create different version of treatment for a files and save all this modification embed in a NEF files, without alter the RAW data. In the same kind of spirit, CaptureNX permit to open JPEG or TIFF files, modify them and save them embedding original file + modication in a single NEF file. In this way, for example, there is no more deterioration of JPEG files due to multiple saving with a destructive format. But, with digikam, if I can see thumbnail for this kind of picture, Digikam seems to be unable to show the prewiew of this image nor load it in editor, so I ask me if support of this kind of NEF files could appear in future realease of digikam. You can find a sample JPEG embed in NEF file here : http://photonoxx.free.fr/digikamNX2/nb-photos-20060528-131503.nef I notice, the thumbnail viewed in Digikam correspond to the modified version, but in nautilus (i'm under Ubuntu 9.10), the thumbnail seems corresponding to the original shot, but nor Fspot viewer, nor Gnome Image Viewer, nor Gimp can open this original file, instead they open the modified version thumbnail (approx. 320x200) and may be Fspot viewer display a bigger version of the modified result but not the embed JPEG. I hope I was not to confuse, and thanks if you find a way to support a little more this kind of file (I don't think about editing, but at least display the bigger preview data).

With the thread about embed JPEG in RAW files, I test the command line to
see property of Embed files in this kind of file : For one created from a TIFF (this TIFF was created from a JPG, but I don't think it's changing something), the exiv2 -pp myfile.nef give this : Preview 1: image/tiff, 320x212 pixels, 203520 octets Preview 2: image/jpeg, 2048x1360 pixels, 1650457 octets Preview 3: image/jpeg, 2048x1360 pixels, 1186804 octets I extract the preview in files and determine which one corresponds to thumbnail (preview 1 but it's not so hard find), to full preview of modified version (preview 2), Embed original file (preview 3 apparently, but at this step, I find ugly to JPEG compress on more time originally TIFF file... but it's a CaptureNX matter ! :) ) I just test with the JPEG embed in RAW I provide here and it's the same thing... So I don't know if Digkam can recognize this kind of nef file, but, if it can, it would be great to use the preview 2 to view the file when we click on this kind of pictures. But it seems it's already what Digikam does for classic Raw files modified by captureNX wich only have thumbnail (preview 1) and jpeg preview at full resolution (preview 2) For NEF files out of the "box" (camera) it's different, there's three embed files one smaller tiff thumbnail (preview 1 - 160x120 instead of 320x214), one very medium jpeg preview (preview 2 - 570x375) probably use to display on the camera screen and a full size jpeg preview (preview 3). So I don't know what it could be do.

Open a file in bugzilla. Attach some dumy nef files to test
Anyway, thanks to Nikon to increase the complexity of puzzle, using or making standard for everyone... I will never buy a Nikon camera... I'm sure...

It's not really depend of Nikon camera but CaptureNX, but I don't know if
similar situation can happened with other RAW format, especially when there's an ability to save with a non destructive manner the treatments made on any image file. In fact, NEF files generated from the start in RAW format are correctly supported as true as Digikam access rightly to the RAW data when editing and show the last modified version made by CaptureNX as preview. This way of work is just the ability to make modification on a photos from JPG file or Tiff file with, keeping in only one file the original picture and all the work made on it as parameters (modification will be computed in realtime in CaptureNX). I think it's a great thing, and very usefull, because the starting picture will be never alter. And for the rest, I think Nikon made anyway good camera ;) For open the file should I open it on digiKam bugs and wishes or on digiKamImagePlugins bugs and wishes on the site bugs.kde.org ?
