Hi,
Maybe I'm missing some setting. When importing raw (.nef files) it doesn't detect exposure time because it seems astap only searches within the filename for that info, although it's in nef file metadata. Am I missing something?

You have to use a special version of DCRAW. It is included for MacOS and Windows version but not for Linux. For Linux It is available form the webpage as debian package and you have to select dcraw-astap in tab stack method.
For Windows and Mac the selection doesn't mater as long you don't select Libraw.
At the moment this metadata is not available from Libraw.

Aamm, ok, got it, Han. But don't fully understand. There are linux programs that are able to extract that information. I guess the don't use nor libraw (which does not support that feature) nor dcraw (I don't have installed the version you mention). So, does that program extract the info by itself? Could astap do the same?
ASTAP does call dcraw and libraw by the commandline. Then normally the metadata is not available. To get the metadata you have to include the source code or call the dll file. I have not done that.
Ok, understood! Thanks Han!
