Darkening blend modes
The following blend modes tend to create a result darker than either of the original images:
Subtract: Darkens all overlapping colors. Whites in the foreground image go black, while
whites in the background image invert overlapping color values in the foreground image,
creating a negative effect. Blacks in the foreground image become transparent, while
blacks in the background image are preserved. Overlapping midrange color values are
darkened based on the color of the background image. In areas where the background
is lighter than the foreground, the background image is darkened. In areas where the
background is darker than the foreground, the colors are inverted. The order of two
layers affected by the Subtract blend mode is important.
Darken: Emphasizes the darkest parts of each overlapping image. Whites in either
image allow the overlapping image to show through completely. Lighter midrange color
values become increasingly translucent in favor of the overlapping image, while darker
midrange color values below that threshold remain solid, retaining more detail. The
order of two layers affected by the Darken blend mode does not matter.
The Darken blend mode is useful for using one image to texturize another selectively,
based on its darker areas. You can also use Screen, Color Burn, and Linear Burn for
variations on this effect.
