fixing color error

Hello,

I use a Canon 50D camera.

last day, for christmas, I used it and I didn't had plan to do it (I
have several cameras), so didn't check it beforehand.

The net result is that I forgot I had used it mast time in "tungsten"
color management, when I shot in day light.

I now have lot of images with excess blue.

I'm not used about color management, because I mostly use my images
without change.

Removing blue don't work. Can you give me some clue? what tool do I
have to use (there are lot under digikam) and in what direction?

I guess I will be able to make a profile and load it on the relevant
images.

thaks

Just adjust the white-balance in post-treatment. It'll be better if you're working on raw files, but it works on jpeg too.

Marie-Noëlle hint let me think that a color temp around 9000 gives a
good result. May be you have a better idea?

No idea, Firefox and Chome show you JPG in blueish taint.

The color temperature, indicated in CanonPr makernote metadata as 3900 °K.

Fix Color temperature in your camera, and all will be fine.

I assume the table cloth is white (or you might find something white or neutral grey in one of the other pictures). By using the color-picker on it, it works fine, and gives a color temperature of 10022,5.
