Why do my Sony A33 RAW files look blue in some editors?

I’m new to shooting RAW. On my Sony Alpha A33, every RAW file appears to have a strong blue cast or “overlay” when I open it in Picasa, GIMP, or Shotwell on Linux. Is this caused by a camera setting, or is it an issue with the software used to open the files?

Have you tried playing with the white-balance settings? The default white balance might not be what you need for these shots, which can give the photos an off-color tinge.

One good thing about shooting in RAW is that you can change the white-balance settings afterwards, so I'd give that a shot.

It’s probably not the camera or the RAW file itself. RAW files need to be interpreted by software, and the color you see depends heavily on the RAW converter and camera profile it uses. Since Picasa, GIMP, and Shotwell may rely on dcraw, an older version may not fully support the Sony A33, which can cause incorrect color rendering such as a blue cast.

A few things to try:

  • Update your RAW software or dcraw/raw converter to a newer version.
  • Test the same file in another RAW editor to see if the color looks normal there.
  • Adjust white balance/color temperature in your RAW processor; RAW makes this easy after the fact.

If other software shows normal color, that confirms the issue is the converter/profile rather than your camera settings. In short: this is most likely a RAW software support problem, with white balance adjustment as a possible workaround.
