Welcome to Camera Bits Forums
I am having a small issue with the thumbnail quality of images converted from RAW to JPG using Nikon NX. The thumbnails are very "chunky" Tested images with Nikon View and windows explorer with better results.
I have uploaded an image at www.imageryconcepts.com/test
I did have it turned off. That helped. Still odd tho. Files generated from ACR looked great. Must be Nikon not playing nice again.
