Planet (Stereographic Projections) Photography is simply crazy and fun! The technique is not only all about skilful digital manipulations, there are a few really good programs that can help you out there, but the raw photography side is very technical. The use of wide angle lenses help to overcome the need for multiple photographs to get the entire scene, but then there is the mapping of your photographs to ensure that you capture all of the surroundings and not to later find a gap in your equirectangular panorama. However, you can avoid the stitching altogether by making do with a single photo and stretch it around in a circle!
