    Hi there !

    I manage my Powershot G2 using Linux "ghoto2". Only recently have I got
    really interrested in the raw images. I have tried 'dcraw' under Linux,
    which works well, but lacks doc as far as "G2" is concerned. I have
    tested various arguments and parameters with 'dcraw' : white balance,
    brightness, highlight management, colour balance and colour space etc..,
    but I would like to know what the best options and parameters are supposed
    to be for the Canon Powershot G2. What I obtained using various blind
    trials, was sometimes satisfactory, sometimes poor or mediocre, but, in
    most cases of a lesser quality than what the camera gives you with direct
    jpg images. The Canon proprietary software (which works only under MSWIN),
    seems to be even more obscure ; it allows only a few options with hardly
    any explaination... True : the jpg images are good, but if you wish to
    modify something you have to save at loss...

    Thanks in advance for any useful input.

    Try ufraw - it's a GUI frontend for dcraw which will allow basic
    manipulation of the image before you save it out.

    Thanks a lot for this advise. I have just installed and tried ufraw, and I
    find this wonderful. The basic manipulation of the image that is
    available, is a lot more than what my version of dcraw allows, at least
    what is proposed in the dcraw man page. In any case, it is a hundred times
    better than what the proprietary Canon software (MSWIN software) offers.

    You're very welcome sir. BTW - I currently am in a canon boycott due to
    their abysmal lack of support for Linux and FWIW, I LOVE my Kodak P850.
