Preservation issues

  • Xena incorrectly guesses the file type as TIFF and normalizes as it would a TIFF, with the result that a very large file (e.g. 70 MB) is normalized to a very small one (eg. 250 KB) with considerable loss of data. Changes to the raw file (ie: alterations done in image editing software) are stored in a separate XMP file, which Xena also does not recognize, and does not normalize together. This means that any edits added by the creator are removed.
  • NEF is a proprietary format with an unpublished specification.
  • NEF files can be very large - 70 MB or more.
