A place for experimental photographers

Equirectangular Panorama

Peirce Quincuncial Projection.

This week I’ve decided to experiment with the Peirce Quincuncial projection. In simple terms, this is a projection which is capable of projecting an equirectangular panorama onto a square. It’s similar to a stereographic projection as both of them represent a 360° field of view. The only difference between them is that a stereographic projection will produce a spherical image whereas Peirce Quincuncial will project the final image onto a square. If you are new to panoramic photography, please familiarise yourself with my previous posts on Equirectangular Panorama as you will need one to follow this step-by-step tutorial.

Stereographic Projections Continued

This post is just a quick update to Stereographic Projections. If you are not familiar with this kind of photography, please read Stereogarphic Projections and Equirectangular Panoramas.

You can easily change the composition of your projections by shifting the centre of your panorama in the panorama preview window, while stitching it in Hugin. If you align the centre of the projection with the Nadir (the point where you were standing when shooting the panorama) you will get the classic circular ‘Little Planet’ effect. If you align the centre of your projection with the Zenith (the point right above the place where you were standing when shooting the panorama) you will get a reversed projection. Obviously, you may also shift the centre to other positions in order to achieve different results.
