This is the view of Geiranger, one of the most popular tourist sites we have and a World Heritage place.
This is a rather strange use of such a wide angle (for me), but since the vista point further up was covered in clouds, I thought I´d try using this wide angle to create the same view. Not the same thing, but still ...

Now that I see this I agree - these corners are HORRID.
