In my experience (Sydney, Australia) they tend to get professionals to shoot with a quality DSLR, then they get pimple-faced Photoshop jockeys to flatten the dynamics and punch in a fake blue sky.

This new extra-wide camera is interesting as it's fairly rare for a consumer-targeted camera to exceed a 24mm (FFE) focal length. Even in expensive professional lenses, getting to 13mm (FFE) is fairly unusual. Most ultra-wide glass stops at 16mm.
