My monitor is a Wide 16:9, res: 2560x1440.
When I started a new save, the game stuck my Field of View (FOV) at 150 for both on-foot and flight. This is how the game takes photos for me at that value:
FOV 150, Steam F12:
FOV 150, In-game mouse-click:
My results corroborate their findings.
FOV 75, Steam F12:
FOV 75, Mouse-click:
If you have them side by side and switch back and forth you will see that there is still some weirdness there.
The big problem for me is that with the FOV that close, I get motion sick, and photography has always been a very important component to exploring in NMS.
I’m hoping this is just another bug and HG will be fixing it in time, along with the others they have on their plate right now.
So if your in-game camera mouse-click is cropping your photos badly, try playing with your FOV setting and see if you can find a sweet spot for your photography.
