The Balcony Panorama

20 September, 2023


With the limited view from a balcony, the result is a half spherical panorama with 180°x180°.
This is quite different from the Tower Panorama.

In the Balcony Panorama, the half sphere is to one side only:


In this example, 6 full frame fisheye pictures cover the 180°x180°:


The 360°x180° equirectangular panorama editor view displays only half the view as expected:


The cropped picture shows the equirectangular projection of the half sphere:


Different projection can be used to minimize the visible distortion.
The Transversal projections are ideal because of the large vertical field of view.

The Transversal Equirectangular projection:


or the edge-of-the-world projection:


The Transversal Cylindrical projection:


The Transversal Mercator projection:


The Transversal Vedutismo projection:


The Stereographic (circular fisheye) projection:


And the little Planet projection:



Compared to the Cylindrical projection:


And the normal rectangular projection.
That wide angle lens has to cover 150°. Good to have a 🐟👁:
