Noise and JPEG processing

I'm less impressed with the JPEG processing on the Samsung NX210 than I was with the NX200's; it's not that it's worse, it's just that even as low as ISO 100 you can get better results from raw. By ISO 400 I see artifacts everywhere -- though not bad artifacts, and frankly I don't think they'll jump out at many people until you hit ISO 800. In contrast, raw-format night photos shot at ISO 3200 looked reasonably good printed at 13x19.
