This image was taken inside the iconic dome of the State Library of Victoria. The room was opened 1913 and was designed to provide room for over a million books and up to 600 readers.
Technique
The shooting was done with a pole which I held at aprrox. 45° over the middle section (as there was a sign which said “no admittance” at the little doors of the central area.) The lens was mounted with a custom-made bracket. Stitched from four images taken with a Walimex (Samyang) 7.5mm fish eye lens on a Sony QX1. Four images around (up, down, left, right). I removed myself by hand in post-processing.
