Somehow I don't trust the whitebalance dialog in digikam. First of all it displays a value different from other program - I shoot in raw using a Canon 300D. If I change the value to the value other programs show (e.g. bibble) the picture is too warm. Secondly what confuses me is that you can change the white balance of a jpeg  picture and not only raw.

What is behind your white balance function?

Somehow I have the feeling that you transform the raw picture to a jpeg and then do some changes to the jpeg. Changes like white balance, saturation, etc. Here you calculate the change but they are not as good as if you would do it to the raw picture. What do you do actually?
