The Ricoh description of this WB mode in the GXR is:
Quote: "The GXR segregates the image into multiple areas and applies the optimum white balance to each. For example, in cases such as where a person is photographed with flash in a room illuminated by incandescent light, even if the subject and background have different color temperatures, both are reproduced with natural colors."
And for the GR they say:
Quote: "When multiple light sources are mixed together, such as sunlight/shade and flash, the camera automatically optimizes the white balance to match each of the separate areas of light. [Default setting]"
But they do say:
"[Multi-P AUTO] is set by default. If the white balance is not how you thought
it would be when shooting an object of a single color or when shooting un-
der multiple light sources, you can change the setting."
I'm not sure how this would be recorded in RAW. Essentially it seems like some in-camera post-capture image processing needs to be done to use this mode, which sounds to me like it's a JPG only mode. But both the GXR and GR seem to record RAWs with this mode.
I wonder how Lightroom handles GR images shot with this WB mode? Since this is the default GR AWB mode, LR must be able to handle it for the GR. And if LR can do it for the GR, it should be able to do it for the K-3. Ditto for the Pentax software.
