By default Gimp doesn't read "raw" files, you need a raw processing pluging
(Nufraw, photozone..). It is possible that what you see is the embedded JPEG
thumbnail and not the full image.

Thumbnails is my assumption too.  Unless space on the card is a
problem, it's usually easiest to save both raw AND jpeg on each shot,
jpegs for quick reminders of the picture, NEF for usable files

If you want to do correction from raw files, you have better use specialized
applications such as RawTherapee or Darktable, especially if you are still
using Gimp 2.8.

I disagree here - for 8-bit colours (gimp-2.8, adequate for many
purposes) ufraw or its successor nufraw work well.  There is plenty
of documentation for ufraw online, nufraw is a fork with some
additions after the original ufraw developer lacked the time to
continue supporting it.

I have nothing against DarkTable, RawTherapee, or Photozone - but
they are all different and set up to do things their own way.  For
somebody who mainly uses the gimp, ufraw or nufraw seem to have a
much less steep learning-curve.

But some of that is the difference between people taking good photos
on good equipment, and a hacker taking snatched photos on "adequate"
equipment.  For example, in many of my W/A shots I have to correct
visible barrel distortion (subjects with a straight line in the
outer part of the view) and with zoom lenses I find that using the
gimp's lens distortion filter I can correct this with a negative
value in the first (main) field, but that value may differ between
shots taken at different times with the same recorded EXIF focal
length.  It's all horses for courses.

The site is devoted to OpenSource photography software (and many
authors of such software use it for support).
