The mausoleum of the family 'von Gans' is the largest gravesite on the central cemetery of Frankfurt am Main. It was erected by Friedrich Ludwig von Gans in 1909. In 1932 it was adopted by the Frankfurt society of cremation. Since then it's used for the burial of urns.
The shooting was done with a 3.15 meter (appx. 10.33 ft) pole to reach a more elevated viewpoint inside the mausoleum. The lens was mounted with a custom-made bracket, which allows me to mount the lens to turn around the no-parallax point of the lens.
As the lens is a fisheye lens, four pictures easily cover 360°. To be sure I took three exposures at each direction. The exposures were 2 f-stops apart. The best exposed set was chosen before stitching.
