By developing a "film emulation" using the supplied "Digital Camera Utility" software, you can take the settings directly from the program and set them into a User Mode in the camera … both the program and the cameras use the same settings
So, take an image, any image that was taken with your camera, that you consider might be "representative", load it into the DCU program and jiggle with the settings until you achieve what you want, then load those settings into your camera.
Take some more pictures, then fine-tune those settings, if needed. After a couple of iterations you should be able to achieve "perfection".
Obviously, these settings only have an effect on .jpg files, so you might want to save RAW+ in the first few instances, so if you want/need to take a step or two back it's easy to do so.
Not a feature I've played with (yet), but there is an option within the DCU to "Load Parameter" and "Save Parameter" within the "Laboratory" section, so having achieved something acceptable with one picture, one can easily apply those parameters to a second (and subsequent) pictures, thereby possibly speeding up the business of generating a profile that "works" with multiple images.
These parameter files are just text files, so might be easily shared!
Unfortunately there's not, as far as I'm aware, any opportunity to copy a parameter file directly to a camera, the details all needing to be entered manually.
It'll be interesting to hear of any success (or failures)
