DaVinci™ White Balance™

The human brain adapts quickly to the current lighting situation, so it can say that for the fact that the piece of paper sitting on the table is actually white, even though is illuminated by the orange light. Cameras also have to make this guess, but are far less efficient at it than the brain is. Some cameras are better than others, but they all make mistakes. That's where this tool comes in handy.

Dropper size dictates how the color is sampled when you click on the image using the dropper tool. 3x3 (default) samples the color of 9 pixels in the neighborhood. 1x1 picks the exact pixel you clicked on.

On the images that don't have anything neutral to click on, you can still use the White Balance by manually selecting the color the image is tinted with. In the above example image is tinted with the blue color, so clicking on the blue color on the color-wheel will put you in the ballpark. All that is needed is to fine-tune it by using the hue (color) and saturation (color intensity) sliders.

And the final result:
