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.
