Ok i need help here please. All my pictures are showing a strong magenta cast. When i set my cameras white balance, i can get it more blue or more yellow, but the magenta/green cast seems to have no effect on the cameras white ballance setting. It only comes right in ACR when i use the white ballance dropper. I see that i can manually set the offset in camera via a graph, but why is this seperate from the 'kelvin' settings? Does the auto WB even look at the magenta/green colour cast? In my studio i use 5800K but the result is still the same if i go higher or lower with the exeption of the image being more blueish or yellowish, the pinkish tint still comes through.
Does anyone know how to get my white balance right from the camera? And is there something wrong with my camera if i have to put a -28 tint on the magenta for every single picture i take, regardless of in camera white balance setting?

The control of Color Temperature (Kelvin scale) lies inherently along the Blue-Yellow axis of the color circle.

Tint is along the Green-Magneta axis of the color circle.

Like this -- you may want to check the Tint setting in your Picture Style.

Another thing to check is to shoot in Raw and in ACR (or the Canon software Digital Photo Professional) choose an appropriate White Balance preset and see if it comes across accurately, and compare the Temp/Tint settings with the As Shot settings.

All that being said, it's hard to say what specifically is causing the problem, since it looks like ACR is properly correcting things when you use the WB eyedropper.

I have and the camera always gives it a magenta tint regardless of my white balance setting. In ACR when i use the white balance dropper to correct the tint, it usually changes the tint to -28 or so. Quite extreme. Just wondering how i can fix this in camera if it possible

when i check white balance with ACR, the temperature stays more or less the same as my chosen in camera setting. It only changes the tint to -28 or so.
Can picture style settings affect RAW images white balance? Im using the portrait picture style. I want to get it right from the camera in order to save time in processing my images.

Is your in-camera color shift setting in the middle?

Well, the WB settings have an effect, but I'm not sure about the fine details of the Tint -- ACR sets both the Temp and the Tint in the WB panel. The camera WB is, well, unclear -- where you set a manual WB it is is using the Kelvin/Temp setting. Then in the Picture Style customizing you have the Color Tone adjustment. And, it goes from "reddish" to "yellowish" which seems to offset the White Balance! And, I haven't tested thing in this to see if the Color Tone is incorporated into White Balance in the image exif so that Lightroom "reads" it. But, it's something to check out.

So, I don't have the answers, just stuff we can explore.
