Apply the Add Grain Operator

You start the process of adding grain the same way regardless if you want to use granularity curves for an existing film stock, or use the Custom option to exactly match the grain of another clip.

To begin the process of adding grain:

1. In the composite, select the layer you want to add grain to, or select an operator (such as Footage) to which you want to add grain.
2. Choose Operators | Grain Management | Add Grain.

The Add Grain Controls panel appears.

3. Select Custom from the Film Stock list.

For more information on the other options, see Using Built-In Granularity Curves. You can still use the Match Grain picker with the other options.

4. To compensate for under or overexposure, set the relative exposure offset using the F-stop field.

The range of permissible f-stop values is from -3 to 3; values entered must be integers.

By default, the Red, Green, and Blue channels are all enabled.

5. If you do not want to add grain to a specific color channel, disable it.
6. Enable Exclusive to show the selected channel as grayscale. This is useful when viewing the blue channel, as the eye is less sensitive to blue than to other colors.

When you enable Exclusive, Red is enabled (selected for display) by default. Click Blue or Green to show either of these channels.

Note: While Exclusive is enabled, any changes made in step 5 (disabled channels) are ignored; you only see the one channel. When you disable Exclusive, all channels become enabled again.

7. Continue the process by analyzing the grain.
