The Swiss Re building, more formally known as 30 St Mary Axe, was completed in 2003 and officially opened in 2004. At 180m its inspiration can be traced back to the Willis Faber and Dumas Headquarters built in 1975 by Fosters and Partners.
The panorama is captured using High Dynamic Ranging, known as HDR, based on 21 photographs from a single nodal point. Bracketing is used to under and over expose each location, resulting in 3 images per 'click point' on the panorama.
Combining these images, prior to stitching, provides a wider range of shadow depth and balanced lighting compared to normal exposures. This is especially important in panoramic imaging due to the range of light levels across a scene.
The panorama can be viewed in full screen via the QuickTime plugin, allowing you to look around the scene in 360x180 degrees at high resolution (2.9Mb)
