EquipmentThe source images were taken with a Canon EOS 5D Mk II, Canon EF 15mm f/2.8 Fisheye lens.
The camera was mounted on a Kaiden Kiwi panorama adapter on a Manfrotto 190XDB tripod with a Bushman Monopole extension lifting the camera to about four metres.
A sky shot and six shots, tilted slightly below the horizontal, were taken. These were at 60° intervals. Each "shot" consisted of seven bracketed exposures from +2 to -2 stops. (The exposures were at shutter speeds: 1/500, 1/320, 1/200, 1/125, 1/80, 1/50, 1/30 all at an aperture of f/16.)
A total of 49 separate images were combined using Hugin (which in turn invokes Nona, Enfuse and Enblend) in order to achieve this High Dynamic Range type result.
