Thanks, wps. Boy, the software guys sure need some standardisation in development.
CedarHouse, wps, I finally found one setting that I needed to change: my RAW output format was set to 32-bit RGB in Assistant Options; should have been 16 bits. But I have to select "Apply tone curve" to get some semblance of sanity.
The screen shot above is the intent for output.
This screen shot (above) is with "Take no action" in the Tone curve selection.
The next is with the AP Tone curve applied.
Closer to the original intent but not quite. I'd still have to edit--I'd still need to boost Exposure, Saturation, Vibrance and possibly Contrast in AP.
Here are the colour space settings in Preferences... in case I've got something wrong there...
Thanks, again.
