Fine-tuning the Grain

Once you have generated or removed grain using the Add Grain or Remove Grain tools, you can manually adjust the response curve for the gain and size in the Animation Editor. The solid curve represents the gain and the dotted line curves represent the size of the grain.

To fine-tune the grain:

1. Use any of the following controls on the Add Grain or Remove Grain UI:

   Use:	To:
   Red, Green, Blue	Adjust the values of the RGB channels for the gain and size of the grain.
   Link	Link the R, G, and B channels of the gain or size, so when you change the value of one channel, the others change as well.
   Save	Save a grain profile for use in other compositions—see Saving and Loading Grain Profiles.
   Load	Load a grain profile you previously saved—see Saving and Loading Grain Profiles.
   Correlations	Specify correlations between the grain present in different color channels. There may be some statistical correlations between the grain present in different color channels depending on the film properties and development process.
   Pixel Ratio	Adjust the discrepancies between pixel aspect ratio and grain aspect ratio.
