Original Note:
The curvature calculator used does not take refraction or observer height into account A better calculator can be found here: http://walter.bislins.ch/bloge/index.asp?page=Advanced+Earth+Curvature+Calculator Using this calculator we will find that the amount of mountain visible in the photo is ~545m without refraction and ~793m with standard refraction
