Explore the other controls in the Background tool.
Highlights Glow. Adjusts the brightness of the brightest areas of the background, adding a soft glow.
Warmth. Refine the color temperature of the background by adjusting the amount. A negative value will cool the image by adding a blue tone, and a positive value will warm the image by adding a gold tone.
Depth Correction. Controls where the out-of-focus area begins in a photo. Moving this slider to the left sets it closer to the camera and moves it further away to the right. As a result, the bokeh effect appears stronger or weaker.
Edges Correction. Used to expand or contract the soft edges of the mask; helpful in adjusting the fine details in a mask, like hair.
