There are some absolutely fantastic shots in this thread. Here is my best one so far and it isn't even that good. I have a few more decent ones stored on my XB1, but the share feature is being wonky so I can't upload them right now.
I don't supposed FH2 will be getting a "big shot" mode like the first Horizon? That mode produced some images with ridiculously high IQ. I just checked one of my old FH1 screenshots and it was a 24.3 MB .bmp @ 3840 x 2160 .
