ISO 800 on an XPro2 | 50-140mm at f/2.8
At 100% viewing, I prefer Photo Ninja. It looks smoother, while maintaining detail. The file from Iridient has lots of artifacting, I believe.
I could be using Iridient wrong, as I've only had it for about half an hour, but nothing I do can match the detail and natural look of Photo Ninja.
