G3 RAW conversion

Does anyone know any raw-convcerter for Canon G3 ? which can handle raw to 48bit tiff conversion?

recommendations, please.

Cray,

Other than Canon's own, I don't think you'll get one yet. Third-party developers are apparently still waiting for the updated Canon SDK, but I don't think it will be too long.

Regards,

Dave Coffin wrote a basic decoder that is one C file.
Beware the caveats on the page Re: 48 bit TIFF. But it does work.

It is also only a simple converter - when shooting in RAW mode (at least on a G3) the pure sensor RGB data is dumped into the RAW file. The accompanying THM thumnail is a JPG with EXIF data on the whitebalance, ISO and all other settings chosen at the time of the shot.

Canon's own software uses this to apply whitebalance and sharpening (or special effects like sepia, B&W etc) after the event.

So for example, if you dump a RAW shot under tungsten, even if you set AWB or Tugsten whitebalance on the camera, the RAW will decode to be very colour cast with yellow.

This isn't a fault - it's just a lack of implementation.

Assuming you want to fixup any pictures in Gimp or Photoshop
then it should work for you.

Actually, BreezeBrowser converts G3 RAW, as does Canon's FVU, but neither is able to convert in linear mode yet, since there is a problem with Canon's SDK code. Chris Breeze is waiting on an update, as are other developers I presume.
Till then, you can convert to 8 or 16 bit TIFF, or JPEG of course, with all the parameter selections (WB, contrast, sharpness, etc.) intact.

cheers,
