HDRMultiscaleTransform is a process that uses wavelets to compress mid to large scales, uncovering small details that might be concealed during a histogram transformation. The recent addition of the "To intensity" option has revolutionized this process. This option works in the HSI color space, preserving hue, saturation, and intensity, and integrates a modification to HDRMT by Russel Croman - ColourCorrected HDRMT. Warren Keller from Masters of PixInsight will guide you through the HDRMT process, including the new "To intensity" option. He will also compare it with the CCHDRMT script and demonstrate how HDRMT can be used to reveal hidden details in your images.
