I went to the new campus Westend of the Goethe University of Frankfurt am Main. In Germany the universities represent the highest level of education an individual can achieve. And if you are well educated, you have better opportunities in the labour market. Therefore I think that education is a necessity.
The shooting was done with a 3.15 meter (appx. 10.33 ft) pole to reach a more elevated viewpoint above the square. The pole was extended to its full length. 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 0.7 f-stops apart. The best exposed set was chosen before stitching.
