I'm sure they'd appreciate the clarification if someone >more knowledgeable in this area could reply I have looked at the DCRAW sources last week, and one part that is missing for Pentax PEF format is reading the white-balance as set on the camera and use that as a basis for the conversion. At the moment DCRAW completely ignores that setting, so you have to specify a specific white-balance correction on every image. They use a "green-multiply" and a "blue-multiply" value for that. So what is needed is some code that interprets the Pentax specific white-balance camera settings, and translates that to the proper multiply values for DCRAW. But John Francis has been digging deeper into this stuff so I am pretty sure he will have some more details ...
