Yes, sorry, I should be more specific. When I say that my K10D is almost never right, I mean auto WB in daylight and flash situations. I owned Canon 350d and 40d models, and I almost never had to adjust WB in daylight situations. By daylight I mean all possible outdoor shooting - cloudy, shade, sunny conditions. Also, I used to take a lot of indoor pictures using just daylight coming from wide opened window curtains, and I always had good results.
When I was shooting some really importaint occasions, I shoot raw+jpeg and if I was not satisfied with camera jpegs, I just did it manually.
I don't need all of my pictures to be perfect, because they are mostly family portraits and situations. But, K10D misses the right WB to often for my taste.
Of course, I can always correct WB in Silkypix, but I don't want to shoot raw all the time. I simply don't have enough time to play around with all those raw shots, so I would like to have the confidence in my camera to do it for me.
That's why I ask about K-x auto WB, because I hope that it does it better than K10D.
Here are few examples. All pictures are developed from raw in Silkypix. First picture is Camera WB, second manual WB, or the one that seems right for my taste.
