Using the Apply Image command
The Apply Image command lets you blend one
image's layer and channel (the source) with a layer
and channel of the active image (the destination).
To use the Apply Image command:
Open the source and destination images, and
1
select the desired layer and channel in the desti-
nation image. The pixel dimensions of the images
must match for image names to appear in the
Apply Image dialog box.
Note: If the color modes of the two images differ
(for example, one image is RGB and the other is
CMYK), you can copy a single channel to another
channel between images, but you cannot copy a
composite channel to a composite channel in
another image.
2 Choose Image > Apply Image.
3 Choose the source image, layer, and channel
you want to combine with the destination.
To use all layers in the source image, select Merged
for Layer.
4 Select Preview to preview the results in the
image window.
5 Select Invert to use the negative of the channel
contents in the calculation.
6 For Blending, choose a blending option.
For information on the Add and Subtract options,
see "About the Add and Subtract blending modes"
on page 196.
For information on other blending
options, see "Selecting a blending mode"
in online Help.
7 Enter an opacity to specify the effect's strength.
Select Preserve Transparency to apply the
8
results only to opaque areas in the result layer.
Select Mask if you want to apply the blending
9
through a mask. Then choose the image and layer
containing the mask. For Channel, you can choose
any color or alpha channel to use as the mask.
You can also use a mask based on the active
selection or the boundaries of the chosen layer
(Transparency). Select Invert to reverse the
masked and unmasked areas of the channel.
(See "Using channel calculations to blend layers
and channels (Photoshop)" on page 194.)
Click OK.

Using the Calculations command
The Calculations command lets you blend two
individual channels from one or more source
images. You can then apply the results to a new
image or to a new channel or selection in the active
image. You cannot apply the Calculations
command to composite channels.
To use the Calculations command:
1 Open the source image or images. The pixel
dimensions of the images must match for image
names to appear in the Calculations dialog box.
2 Choose Image > Calculations.
Select Preview to preview the results in the
3
image window.
Choose the first source image, layer, and
4
channel. To use all the layers in the source image,
choose Merged for Layer.
