Just wanted to give an update on color moire removal with the latest stable dt v1.2.3. I have found that if I use wavelet profile denoising and set the blend mode to color, I can almost totally rid the image of color moire by cranking the strength up as high as it will go. Weaker moire patterns will need less. Would be nice to get some confirmation of this with other cameras.
