5. How was this done?

The source images for the VR panoramas were shot with different Nikon DSLRs, with an 18mm lens, using RAW mode, followed by HDR processing. A Kaidan Spherical VR head was used to orient the overlapping images. PTGui Pro was used to stitch the panoramas. Pano2VR was used to make the original VR tour. For the HMD tour, krpano was used. Alexandra Gurevich, my 2014-2015 graduate research assistant at the University of Nevada, Reno, was instrumental in getting the HMD tours completed. Hopefully at some time we will return to Ireland and re-shoot everything in 3D.
