Pls note Mark's comment above - AWB is not applied to RAW images. Hence what you see when you play with the sliders in RAW...

In operation on JPG's, AWB just applies to the image the preset WB settings from the built-in selection of WB settings the camera has - Daylight, Tungsten, Kelvin, Flash etc. AWB is not a continuously variable parameter when applied to JPG's produced in camera. I'm pretty sure of that.
Check it out yourself, it's easy to prove. Just shoot a series of RAW+ images with the camera set to AWB, take two shots on a bright sunny day, open sky then green grass and then open them in ACR, check the tint and colour temp values. In fact if you just shoot slightly different areas of open sky you're liable to see a slight change of colour temp and tint.

strange colour balance problem on KX

Hi, so far I've not had this problem on my new KX but I have full empathy with your bewilderment because my GX10 does this sometimes. It is a rare problem though and you'll drive yourself crazy trying to find out why the camera alters colour balance by itself when the conditions don't dictate such a change.

I see this as a design fault in the Pentax colour balance system.

There is no solution!

The work around is to set Raw plus jpeg and reduce your jpeg size to 6 megs if you have card space issues. Alternatively, set the color balance to suit the conditions before using the camera.

A more extreme solution is to dump Pentax and get a better camera!

As I've said before, auto white balance is just guessing. And *all* digital cameras - every single last one of them - will sometimes guess wrong. That's life with AWB. If you care that much, set WB yourself, or shoot RAW. Again, that's true for every digital camera ever made.
