Just trying this interesting technique. It's easy to do but the end result depends a lot on location. I tried 4 in a small park/playground. I think the first and last turned out best, but I definitely must find a better place for this.

Btw, lens was Samyang 12mm/2.0 on a Sony NEX-6, not that it matters much.

I like the last the most due to the basketball court. Nice. |

In short those are 360°x180° equirectangular panoramas remapped into a stereographic projection.
Longer explanation: I shot from a tripod of course and using the 12mm Samyang I shot 3 rows of 6 images (total 18 photos) to cover the scene in all 360 degrees and from floor to sky (almost 180°). You must use manual mode so that all the images get exactly the same exposure. First thing was to process the 18 raw images with RawTherapee all with exactly the same settings. Then I stitched them all together with Hugin using equirectangular projection. Then I used Hugin for a second time to remap this stitched image with stereographic projection. The projection is rotated by 90° in the second dimension (I forget which it is, either pitch or yaw) and arbitrarily in the third (roll) to get a nice compositional balance. In the exported image I then filled the hole in the middle where the tripod legs would be using Gimp, and also fixed some minor stitching errors and did the normal postprocessing steps. Simple really.

I will study this carefully and then maybe I will be able to do it. Thank you! |

Maybe I should document the process in detail and with screenshots. I was following a tutorial but it wasn't very specific and it took me a while to figure it out. I'll try to remember to do it the next time I do this kind of thing (which should be soon, I already have ideas!) and I'll post them here.
