Unless I missed something, I don't think anone suggested otherwise.

Anyhow, what cracks me up (sort of) about this is that it appears the K-7 has done exactly what people have been begging camera manufacturers to do for years - to make the AWB aggressive enough to completely remove a color cast from yellow/orange lighting. That's what people say they want when shooting indoors in tungsten lighting, anyhow. But then when the camera does the same thing outdoors - removing the yellow/orange cast from the sunlit areas, thus leaving the color flat and the shadows blue - they are not happy.

I think WB is not stored as a single number, but a whole complicated slew of numbers representing the intensity of the light at different wavelengths, from which a RAW converter calculates a WB value. At least, I've heard that's the case for DNG; perhaps PEF has a single field somewhere in an undocumented makernotes field or something.

I'd suggest it's the other way around, depending on what you mean by "fooled". The K-7, as mentioned above, appears to have done exactly what people have been begging cameras to do under tungsten light for years.
Marc, you are right, as you almost allways are, I translated "broken converter" to "using a broken TC".
And I also agree with you that Pentax did what "people" wanted. Pentax aimed to get the tungsten light corrected.
Now they will have good scores in the review tests.
Unfortunatly, I can recognize tungsten situations much more easily than outdoors yellow conditions..... I'd rather have it behave somewhat more like my K10D.

Agreed. FWIW, I shoot RAW, so I don't worry much about the camera's AWB, but my favorite WB setting to apply in PP is Flash. It's about as neutral as you can get, so it does a great job of preserving the "golden hour" type of light, as well as rendering sunsets and other potentially tricky natural lighting situations well.

I was surprised to read you had your custom option set to make the adjustment for tungsten "subtle". Well, I didn't realize there was such an option (nice touch, K-7!) but once someone pointed it out, I was sure that would turn out to be it. Guess they must have tweaked even the default behavior.
