Here is the most simple fix. it just changes the default saturation. obviously this does not work for every, but for me using only 40D, it makes life easier.

there seem to be per camera conversion matrices in librawstudio/rs-adobe-coeff.c but i think it is identical to the one in dcraw.

so what does rawstudio do differently from dcraw -w?
