Apple Shake 4 - Manual (Page 874)

874 Chapter 28 Filters
Shake uses the seed value as the basis for generating a random value. Using the same
seed value results in the same random value being generated, so that your image
doesn’t change every time you re-render. Use a single value for a static result, or use
the expression “time” to create a pattern of random values that changes over time.
For more information on using random numbers in expressions, see “ Reference Tables
for Functions, Variables, and Expressions ” on page 941.

stdDev
This value is multiplied by the amount parameter. A higher value indicates more
variation in the grain, making it more apparent. This parameter defaults to 0.5.
The rStdDev, gStdDev, and bStdDev subparameters let you control the variation within
each individual color channel. By default, these three parameters are locked together.
softness
Blurs the edges of the grain that’s introduced. This parameter defaults to 1.2. The
rSoftness, gSoftness, and bSoftness subparameters let you control the grain softness of
each individual color channel.
