Spatially Varying White Balance

An HDR image suffering from incorrect while balance (yellow cast in the upper left corner) is corrected by locally manipulating the color temperature. Two strokes were sufficient to perform this correction. One stroke was used to specify the correction at the upper left corner, while another prevents this correction from propagating to the rest of the image.
