This image is from the August page of my 2018 calender. This image shows a remapped photosphere and was taken inside the orchestra shell of Oberstdorf (Bavaria, Germany). Reprojection is little planet (stereographic down).
This image is from the July page of my 2018 calender. It’s the center part of a larger panorama. The projection is rectilinear. I used a neutral density filter with 10 f-stops to get an exposure time of 8 seconds.
