Ben -
You should do a test with Basiccolor Input to check that your Dcraw
settings are ok. Although I'm not sure whether the current Basiccolor
is working well.
Graeme -
For "accurate" SLR profiling what one really needs is simply to
establish the primaries - a matrix, no shaper or LUT is sufficient.
There should be an option for this in Argyll. Although for all I know
there already is :)
