Suggested uses: The Overlay blend mode is particularly useful for combining areas of vivid
color in two images.
Soft Light
Soft Light is similar to the Overlay blend mode. Whites and blacks in the foreground
image become translucent, but interact with the color values of the background image.
Whites and blacks in the background image, on the other hand, replace the foreground
image. All overlapping midrange color values are mixed together, creating a more even
tinting effect than the Overlay blend mode.
The order of two objects affected by the Soft Light blend mode is important.

blacks in the background image, on the other hand, interact with overlapping midrange
color values in the foreground image.
