Chapter 17 Layered Photoshop Files and the MultiLayer Node 477
Importing a Photoshop File Using the FileIn Node
If you don’t want to import every layer within a Photoshop file, you can simply use a
FileIn node, as you would with any other media in your script. When you do this, you
have the option of reading any single layer from that file into Shake.
To import a Photoshop file using a FileIn node:
m In the Image tab, click FileIn and navigate to the Photoshop file in the File Browser.
Select the file (or files), then click OK.
By default, the image is imported as merged.
Exclusion The second image acts as a mask for inverting the first image. White
areas of the second image completely invert the first image; black areas
of the second image leave the first image unmodified.
HardLight Screens or multiplies the first image, depending on the strength of the
second image. Values below 50 percent in the second image multiply
the first image, making it darker. Values above 50 percent in the second
image act as a Screen effect. Values of pure black or white in image 2
replace image 1.
Lighten Identical to Max. Takes the maximum value when comparing two pixels.
Good for adding mattes together.
LinearBurn Similar to ColorBurn, except it decreases brightness, not contrast, to
darken the first image. Whites in the second image do not modify the
first image.
LinearDodge The opposite of LinearBurn, brightens the first image. Black areas in
image 2 leave the first image unaffected.
LinearLight A combination of LinearBurn and LinearDodge. Values above 50 percent
in image 2 increase brightness of the first image. Values below 50
percent darken the first image. Values of pure black or white in image 2
replace image 1.
Overlay To shade an image. 50 percent in the second image keeps the first image
the same. Brighter pixels brighten the first image, darker pixels darken it.
PinLight Performs Min or Max, depending on the strength of the second image. If
the second image is brighter than 50 percent, a Max (Lighten) is
performed. If the second image is darker than 50 percent, a Min (Darken)
is performed. Values of pure black or white in image 2 replace image 1.
SoftLight Raises or lowers brightness, depending on the strength of the second
image. Values above 50 percent in the second image decrease the
brightness of the first image; values below 50 percent increase the
brightness.
VividLight Raises or lowers contrast, depending on the strength of the second
image. Values above 50 percent in the second image decrease the
contrast of the first image; values below 50 percent increase the contrast.
