1. Create multiple previews that cover background & dim structures. (Ignore high signal areas) - For Layer 1 a threshold of 3.0 - 5.0 is normal - It's best to increase number of iterations rather than the amount. - Apply the process to each preview or use a Real-Time Preview. 2. Click the 'Preview Mask' box to ensure that the mask is protecting all high signal areas (coloured black) 3. For the Target you can: - Do one pass with 'RGB/K components' selected. OR - Do one pass with 'Chrominance' selected, using agressive settings. - Do one pass with 'Luminance' selected, using more reserved settings. ***To define which Target option you need to check the chrominance part of the image to determine how much noise exists. 0.25,0.5,0.25,0.5,1,0.5,0.25,0.5,0.25 0.5,1,0.5 0.5,1,0.5 0.8003,0.2729,0.1198,0.0578,0.0287,0.0143,0.0072,0.0036,0.0019,0.001 Linear Interpolation (3)
