•
Hard Mix: Similar to the Hard Light blend mode, except that the saturation of overlapping
midrange color values is intensied, resulting in extremely high-contrast images. Whites and
blacks are preserved. Although the order of two layers doesn’t aect the overall look of two
images blended using the Hard Mix blend mode, there might be subtle dierences.
Inversion blend modes
The following two blend modes create results that often appear to resemble aspects of a
photographic negative of the selected layer.
•
Dierence: Similar to the Subtract blend mode (in the Darkening category), except that areas
of the image that would be severely darkened by the Subtract blend mode are colorized
dierently. The order of two layers aected by the Dierence blend mode does not matter.
•
Exclusion: Similar to the Dierence blend mode, except that the resulting image is lighter
overall. Overlapping areas with lighter color values are lightened, while darker overlapping
color values become transparent. The order of two layers aected by the Exclusion blend
mode does not matter.
Blend modes that manipulate alpha channels
The Stencil and Silhouette blend modes let you use a single layer’s alpha channel or luma
values to isolate regions of background layers and groups. (Similar eects can be accomplished
using shape and image masks. In addition, masks might provide you with a greater degree of
control, depending on your needs. For more information, see Shapes, masks, and paint strokes
overview on page 828.)
Stencil modes crop out all non-overlapping parts of layers underneath the layer used as the
stencil. Silhouette modes do the opposite, punching holes in overlapping layers underneath in
the shape of the layer used as the silhouette.
