Thanks for the reply.
What should banding supression be set at? and the Color Noise Supressions tab should it be set at default?
Also, with sharpening what has been your experience in the setting?
I leave the noise suppression sliders at full left, banding suppression at full left, pattern noise suppression unticked. In preferences, I disable sharpening on output (If you wish, you can leave sharpening at 34/3 so you can work with a lightly sharpened file while in RAW, and still output an unsharpened file).
