 A
clipping mask creates a shape mask, pixel for pixel,
regardless of hue or saturation. Opacity does, predictably,
alter the clipping mask effect. Some masks take advantage
of this by using hue and opacity, with Photoshop’s
many blending modes. We call these Dual Purpose.
Following
the steps in Part 1, using a dual purpose clipping
mask, A, with the original image, B, we get C: |
|
|
|
A |
B |
C |
|
|
| |
|
|
To take advantage
of the dual purpose clipping mask, duplicate the clipping mask
layer and drag it above the image. We suggest locking the two
clipping mask layers, so that you can reposition them is you want.
Set the clipping mask to the image (see Part 1). Adjust the blending
modes and/or the blend if sliders in the Layer Styles dialog box
(in early PS version, it comes up clicking Layer Options in the
Layer Palette Menu). |

C is the clipping mask. It
is duplicated and moved to the top, A. A and C were locked together:
In CS activate the layers you want to link (Ctrl click on the
Layers) then click the link icon at the bottom of the Layer Palette
(circled). |
|
In earlier versions, you
activate the top layer and
click in the box next to the eyeball. |
| |
|
|
| After this, you adjust the blending
modes and/or the blend if sliders: |
| |
|
|
 |
|
 |
| |
|
|
Open the Layer
Styles dialog or Layer Options palette in early versions of Photoshop,
for the top layer. Slide the white “This layer” triangle
to the left until the middle of the image disappears. If you hold
the Alt key down as you click and drag the triangle it will split
and you can have a more subtle setting. When Blend If is what
you want, click okay. Then play with the layer’s blending
modes in the Layers Palette: |
