Studio Artist’s image operation effects include one called White Balance, which you can use to automatically correct the white balance of an image. Today’s post will take a quick look at using the White Balance effect to balance the nighttime lighting in a processed image.
The 2 images above show an effected image before and after processing with the White Balance image operation effect shown below.
I generated the initial effect by processing a segment of video taken at nighttime with the Temporal Scan Tracker temporal image operation effect. The combination of the temporal processing along with the night lighting in the original video frames gives the effected image an orangish hue cast. I wanted to balance the white point of the lighting in the scene to remove the orangish hue cast and get a better representation of the actual image coloring in the original scene.
The White Balance image operation effect tries to automatically adjusts the white balance of a scene to remove any biased hue color casts in the image. You can see in the images shown above that the second white balance corrected image non longer has an orangish hue cast to it.
