Layers and Masks 39
As a property of individual layers, a layer's blend mode determines how
each pixel on that layer visibly combines with those on layers below.
(Because there are no layers below the Background layer, it can't have a
blend mode.) Note that changing a layer's blend mode property doesn't
actually alter the pixels on the layer—so you can create different blend
mode effects after creating the image content, then merge layers when
you've achieved the result you want.
As a property of certain 3D layer effects, where the blend mode is one of
many settings that determine a color change superimposed on the layer's
pixels. The effects themselves are editable and don't alter the actual pixel
values—nor does the effect's blend mode alter the layer's blend mode
setting.
For an illustration of the individual blend modes, see "blend modes" in the
PhotoPlus Help’s index.
A tool or layer's Opacity setting interacts with its blend mode to produce
varying results. For details, see Adjusting opacity/transparency on p. 40.
To set a tool's blend mode:
Select the tool and use the drop-down list (displays Normal by default) on
the tool's Context toolbar.
To set a standard layer's blend mode:
Select the layer and choose the mode from the blend mode's drop-down list.
It's also possible to include or exclude tones or colors to be included in any
blending operation by using blend ranges. For more details, see PhotoPlus help.
