650 Metres.

I am standing 650m away from Chancelot Mill. Assuming I change the viewpoint, by moving around the circumference created by this 650m radius, by 1 metre every time I take a step to my left, I will achieve 4,082 different viewpoints of the mill. But that is only standing 650m away. Now imagine me taking one step forward to create a 649m radius and then doing the same maths type thing I just did. I can't be arsed doing that maths type thing 650 times so all I will say is that there is 'quite a lot' of photographs still to take.

The point is that each one would still be a photograph of the mill. The numbers are immaterial. They always are.

By the way, you can see the mill from Fife.
You do the math.
