Shot at a pretty high ISO, since I was using a circular polarizer and the light was fading. Digikam really does a great job of luminance noise reduction; with my noisier shots I’m exporting from there, with RAW noise reduction set to about 80-100, and then doing a selective Gaussian blur and unsharp mask in GiMP, both at a threshold of about 15-30, depending on the shot. The selective blur cleans up the last bits of noise in defocused areas, and the sharpness just tightens things up a bit.
