I processed the same raw with DPP v4.3.3.1 and ACR v9.1.1. Check below. I guess it is moire effect or some very similar art effect visible in DPP only? In DPP I tested both Neutral and Standard picture Styles. Got the same. ACR is free of this art effect. Any idea why? Raw original file for processing/demo purposes only is available here, so please check with your raw converter. I used 16 bit tif conversion for both.
Thanks for comments!
