These panoramic images were taken inside Marienberg Fortress (German: Festung Marienberg) in Würzburg. The Fortress Marienberg is a symbol of Würzburg and served as a home of the local prince-bishps for nearly five centuries.
Technique:
The shooting was done with a 1 meter (appx. 3 ft) pole which I held straight over my head. The camera was a Ricoh Theta Z1. The RAW images were optimized in Lightroom and stitched with the plugin for Lightroom. Cleanup of the nadir was done with Pano2VR.
