ADOBE PHOTOSHOP 6.0 217 User Guide To specify opacity for a layer: In the Layers palette, enter a value in the Opacity text box, or drag the Opacity pop-up slider. You can also specify opacity in the Layer Styles dialog box (Photoshop) and in the Layer Options dialog box (ImageReady). (See "Using the Layer Style dialog box (Photoshop)" on page 220 and "Specifying layer properties" on page 219.) Specifying layer blending modes You use layer blending modes to determine how the pixels in a layer or set of layers are blended with underlying pixels in the image. By applying modes to layers, you can create a variety of special effects. For a description of each blending mode, see "Setting options for painting and editing tools" in online Help. When working with layer sets, you can use Pass Through blending. Pass Through blending allows the blending modes and adjustments of the layers within the set to interact with the layers outside the set. (For more information on Pass Through mode, see "Grouping layers into sets" on page 213.) Note: There is no Clear blending mode for layers. In addition, the Color Dodge, Color Burn, Darken, Lighten, Difference, and Exclusion modes are unavailable for Lab images. To specify a blending mode for a layer: In the Layers palette, choose an option from the Blend Mode menu. You can also specify a blending mode in the Layer Styles dialog box (Photoshop) and in the Layer Options dialog box (ImageReady). (See "Using the Layer Style dialog box (Photoshop)" on page 220 and "Specifying layer properties" on page 219.) Locking layers You can lock layers and layer sets to make certain properties of a layer unchangeable. When a layer is locked, a lock displays to the right of the layer name. The lock is solid when the layer is fully locked so that no editing is possible; it is hollow when partially locked. For example, a layer is partially locked when you lock the layer position so its contents cannot be moved using the move tool. Locked layers can be moved to a different location within the stacking order of the Layers palette, but they cannot be deleted. When a layer is fully locked, you cannot edit the pixels, move the image, or change the opacity, blending mode, or layer style applied to that layer. You can lock transparency to confine your painting and editing to those areas of a layer already containing pixels. For example, you may want to edit an object (adding special effects, changing color) without adding pixels to the transparent area outside the object. You can also lock the image to prevent inadvertent pixel changes or movement of the image and yet still allow the blending mode, opacity, or layer style to be edited. For example, you can edit the layer mask of a layer with locked pixel data. This is very useful when doing montages.

User Guide
To specify opacity for a layer:
In the Layers palette, enter a value in the Opacity
text box, or drag the Opacity pop-up slider.
You can also specify opacity in the Layer Styles
dialog box (Photoshop) and in the Layer Options
dialog box (ImageReady). (See “Using the Layer
Style dialog box (Photoshop)” on page 220 and
“Specifying layer properties” on page 219.)
Specifying layer blending modes
You use layer blending modes to determine how
the pixels in a layer or set of layers are blended with
underlying pixels in the image. By applying modes
to layers, you can create a variety of special effects.
For a description of each blending mode,
see “Setting options for painting and editing
tools” in online Help.
When working with layer sets, you can use Pass
Through blending.
Pass
Through
blending allows
the blending modes and adjustments of the layers
within the set to interact with the layers outside the
set. (For more information on Pass Through
mode, see “Grouping layers into sets” on
page 213.)
Note:
There is no Clear blending mode for layers.
In addition, the Color Dodge, Color Burn, Darken,
Lighten, Difference, and Exclusion modes are
unavailable for Lab images.
To specify a blending mode for a layer:
In the Layers palette, choose an option from the
Blend Mode menu.
You can also specify a blending mode in the Layer
Styles dialog box (Photoshop) and in the Layer
Options dialog box (ImageReady). (See “Using the
Layer Style dialog box (Photoshop)” on page 220
and “Specifying layer properties” on page 219.)
Locking layers
You can lock layers and layer sets to make certain
properties of a layer unchangeable. When a layer is
locked, a lock displays to the right of the layer
name. The lock is solid when the layer is fully
locked so that no editing is possible; it is hollow
when partially locked. For example, a layer is
partially locked when you lock the layer position
so its contents cannot be moved using the move
tool. Locked layers can be moved to a different
location within the stacking order of the Layers
palette, but they cannot be deleted. When a layer is
fully locked, you cannot edit the pixels, move the
image, or change the opacity, blending mode, or
layer style applied to that layer.
You can lock transparency to confine your
painting and editing to those areas of a layer
already containing pixels. For example, you may
want to edit an object (adding special effects,
changing color) without adding pixels to the
transparent area outside the object. You can also
lock the image to prevent inadvertent pixel
changes or movement of the image and yet still
allow the blending mode, opacity, or layer style to
be edited. For example, you can edit the layer mask
of a layer with locked pixel data. This is very useful
when doing montages.
