Reversing the two overlapping images results in subtle differences in how the
overlapping midrange color values are mixed together.
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.
The order of two objects affected by the Linear Light blend mode is important.
Pin Light
Pin Light is similar to the Hard Light blend mode, except that overlapping midrange
color values are mixed together differently based on their color value. 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.
