To clarify any points about my current jobs in digiKam, these are fresh new about 16 bits/color/pixel and RAW files support :

1/ RAW file support in 8 bits/color/pixel complete on my computer. showfoto and image editor can load (not save) all RAW file format supported by dcraw program. I have also fixed parsing code to identify RAW files with current dcraw::parce.c implementation. This is fix any problem with DNG file format.
This code is ready to commit. I will done it after 0.8.0 release date planed to november 15.

2/ DImage is currently in development and based on Renchi Raju implementation :
  - RAW files can be loaded in 16 bits/color/pixel using dcraw.
  - TIFF files can be loaded in 8/16 bits/color/pixel.
  - PNG files can be loaded in 8/16 bits/color/pixel
  - JPEG files can be loaded and saved in 8 bits/color/pixel. All metadat are preserved (JPEG/IPTC/COM).
  - ALL others image file format are loaded using QImage interface in 8 bits/color/pixel.
  - TODO  : 
       * writing save PNG/TIFF methods
       * writing load/save PNM methods in 8/16 bits/color/pixel.
       * writing save digikam comments in PNG and PNM (like with JPEG files)
       * Metadata support for TIFF file (IPTC).
       * image editor and showfoto intergration (acutally DImage works with a dedicaced small image viewer based on image editor canvas).
       * Fixed all image filters in digikam/libs to support 16 bits/color/pixel.
       * Fixed all image plugins in digikam core and DigikamImagePlugins to support 16 bits/color/pixel.

... And that all for 0.9.0 release (outch...)

If there are any volonters to help me in this large task, please let's me hear...
