[digiKam-users] --> EXIF information on NEF and PNG

[Gilles Caulier]

Hi,

NEF is a RAW container including Exif, Makernotes, and sometimes XMP
metadata set by camera. This is true for all RAW files based on TIFF/EP
standard, even if RAW format extend the tags list with proprietary values.

In all cases whole Exif are there and mandatory to be post processed with a
software as Capture NX. Demosaicing process need to know all shot
conditions.
