Aspect Ratio
This slider adjusts the aspect of the grain so that it can be matched with anamorphic images.
Alpha-Multiply
When enabled, this checkbox multiplies the image by the Alpha, clearing the black areas of any
grain effect.
Spread Tab
The Spread tab uses curves for the red, green, and blue channels to control the amount of grain
over each channel’s tonal range.
RGB Checkboxes
The red, green, and blue checkboxes enable each channel’s custom curve, allowing you to
control how much grain appears in each channel. To mimic usual film responses, more grain
would appear in the blue channel than the red, and the green channel would receive the least.
Right-clicking in the spline area displays a contextual menu containing options related to
modifying spline curves. A complete description of the LUT Editor’s controls and its options can
be found in Chapter 45, “LUT Nodes.”
In and Out
This control provides direct editing of points on the curve by setting In/Out point values.
Examples
Default Spread
In the default setting, the grain is applied evenly to the entire image, as shown here.
However, film often shows a different amount of grain in the blacks, mids, and whites.
