Background goes from white to blue

[KevinCarter]

Shot a subject outside on white background, the background goes from white to light blue, very strange, anyone have any idea on it? thanks

Assuming you're using AWB, I would expect that it's not coming up correctly in whatever you're using to view it. If you're using something like Lightroom, I would suggest you try another white balance, or auto.

What you're seeing is a change in the white balance across the wall, and at the "blue" end, it's just that you're getting more reflection from the sky, or possibly that you're shooting indoors, and the bluer end of the wall is closer to a daylight ambient light source compared to the yellower colour temp of an incandescent/halogen light source.

I come across this sort of thing a lot shooing interiors and kitchens, especially with the predominance of white walls and ceilings.

My guess is the whole thing is white balanced slightly blue, but the hotter areas are over-exposed so they're just showing up as white. In the darker/shadowed areas, you're seeing the blue.

thanks guys, not sure now. I save a screenshot next time see it.
