Field tips
There are many lines at this location, so creating an aligned photo is key. Stand in the center of the hallway, with the light direct above you, to create a sense of symmetry and to make sure that all of the lines are parallel.
This viewpoint is only achievable with a wide-angle lens (28mm). If the lens is too narrow, you won't be able to incorporate the light on the ceiling.
For an unexpected focal point, try adding a model in the shot.
