Linear Light
Linear Light is similar to the Hard Light blend mode, except that overlapping midrange
color values are mixed together with higher contrast. Whites and blacks in the foreground
image block the background image. Whites and blacks in the background image, on the
other hand, interact with overlapping midrange color values in the foreground image.
Overlapping midrange color values are mixed together. Lighter background colors brighten
the foreground image, while darker colors darken it.
