Keeping EXIF data alive

Hi,

I use digiKam to edit my RAW images and finally store them as JPG(2000). Now
digiKam kills my EXIF data and I just wondered if it's a "bug" or my fault
that all EXIF data is being deleted while editing.

As far as I can see there is even no color space assigned to the photos …
looks like something is going horribly wrong here … any ideas about that?

regards

Knut

Which version of exiv2 and libkexiv do you use? Please check that your
version of exiv2 can write metadata to this format.
