I finally got some time to take my kit out for some night photography, and went to the South Bank last night - it was a full moon and I was pretty happy with my results (will post them in a seperate thread). The problem is that post RAW processing is showing quite a lot of noise and worse, some blotchiess and colour banding in the sky. The noise I can fix in Noiseware but the banding looks bad in some of them and will almost certainly be rejected by istock I always shoot ISO 100 and I have noticed the same noise and banding at 4sec and 30sec, so exposure time seems to make no difference I've tried playing around with CS2 RAW settings and luminous smoothing set to 99% seems to help but not much. The original raw image when viewed in the preview pane (pre-processing) doesn't seem to exhibit the same noise and banding?? Any tips, suggestions??
