Suggested uses: 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.
Multiply
Like Darken, Multiply emphasizes the darkest parts of each overlapping image, except
that midrange color values from both images are mixed together more evenly.
Progressively lighter regions of overlapping images become increasingly translucent,
allowing whichever image is darker to show through. Whites in either image allow the
overlapping image to show through completely. Blacks from both images are preserved
in the resulting image.
The order of objects affected by the Multiply blend mode does not matter.
Suggested uses: The Multiply blend mode is particularly useful in situations where you
want to knock out the white areas of a foreground image and blend the rest of the image
with the colors in the background. For example, if you superimpose a scanned sheet of
handwritten text over a background image using the Multiply blend mode, the resulting
image becomes textured with the darker parts of the foreground.
