One point perspective is a powerful tool, creating tunnel-like symmetry and focus on whatever is at, or in front of, the vanishing point. But we nearly always use one point as a horizontal tool, looking down a corridor, tunnel, or street.
There is a second orientation which can be utilized for one point perspectives, one that still respects the rectangular geometry of most architecture. That is vertical one point. The image below is an even less common type of one point: an exterior vertical one point perspective. Typically exterior one point shots are reserved for creating powerful visuals in redwood groves or amongst other tall trees.
Here the mix of tall architecture, a convent bell tower, and Cypress trees, provides the encroaching elements from all four sides, which make a one-point work. Lighting provides a second layer to the image. But the single element that adds a living story to the shot is the crow, heading towards its nest in the belfry. The bird, and its relation to the belfry, was sufficiently important to my vision of this image that I took the best shot from the series, then rotated the crow 180 degrees, so that he was flying towards, not away from the nest. Other images had that direction of flight, but not that clarity of silhouette, so this edit offered the best solution to tell the story.
