This image was taken on the Webb Bridge in Melbourne. It spans the Yarra River and the architect is Denton Corker Marshall in collaboration with artist Robert Owen.
Technique
The shooting was done with a pole which stood on the red wall. The lens was mounted with a custom-made bracket. Stitched from five images taken with a Walimex (Samyang) 7.5mm fish eye lens on a Sony QX1. Five images around to get rid of my own shadow (standing left and right of the pole while taking the image(s) which faced the opposite direction of the sun). The zenith and nadir was retouched by hand in post-processing.
