Hi,
I just wonder if NR (noise reduction) is worthy of a star trail photo taken by a long exposure, e.g., 30 min. It'll take another 30 min to finish NR after shutter is closed. Is the NR effect equivalent to the long waiting time? (I guess that after shutter is closed, the camera, etc. can be moved away from the scene while NR is still on.) Would anyone share opinions and examples from experience? Thanks for your response.
