Yes, the Center for the Arts. No noise reduction deliberately applied
although I discovered that ACR was applying a value of 25 on color
noise. However, looking at several images and moving both the color and
luminance sliders over their full range I couldn't see where either of
them amounts to a hill of beans in effect on the image.
