Chapter 9, Removing Dust

The infrared (IR) channel is available in DPX and Cineon 10-bit files that contain the SGI byte order. This IR channel is collected during the film scanning process at the same time as the visible colour channels (red, green, and blue). Whereas film is mostly transparent to infrared radiation, dust and scratches are not and therefore appear in the IR channel. Once imported into Lustre, the information contained in the IR channel can be used to detect the appearance of dust and scratches to a higher degree than is possible using standard dust detection techniques.

Note: IR dust detection is only available for the Master Station and the Lustre Station.
