The source images were shot on a Canon EOS 5d with a 16 mm Zenitar fisheye lens.
This 360° panoramic image was shot at dawn on the Winter Solstice 2007 at the ancient stone fort known as Grainan of Ailach, in County Donegal, Ireland. It is also available in Virtual reality form.
Although it is across a county line the people of my home town – Derry – have always regarded Grianan as one of THEIR local historical landmarks, and it would certainly be on the tourist-trail for any visitor to Derry.
Grainan of Ailach literally means “Fortress of the Sun”. In its day it was the Seat of the High Kings of Ulster.
An ancient site such as this is interesting. One such site might be the work of a small group of craftspeople talented in the use of stone. But I really began to take notice when I discovered that there were structures like this all over Ireland …
[150 miles away on Inishmore Island.]
That implies a society with travel and some means of, if not designing, at least of recording and copying. But perhaps, just perhaps the society here, three thousand years ago, had specialists who designed, who built, who advised on the choice of stone, who managed great projects such as this.
That makes them seem so much more like us and puts our puny advances in the intervening years into the context of our hundreds of thousands of years of social development since we emerged as a species.
The panoramic image was created by combining 27 separate digital photographs covering every angle and with bracketed exposures. Hence the detail has been captured both in the brightest areas of the sky and in the shadows inside the fort.
The source images were shot in groups of three (bracketed with +2 and -2 stops) as Canon Raw images. They were stitched and blended together using a free, open source, program called Hugin. Hugin in turn invokes a program called Enfuse to create the HDR (High Dynamic Range) effect.
The source images were shot on a Canon EOS 5d with a 16 mm Zenitar fisheye lens.Because of the way that it was created this is a very high resolution image (the equivalent of about 80-megapixels). It is capable of delivering very fine detail even when printed at massive sizes.
I have written a short journal entry introducing the method by which these panoramas are created, it is called:
“Creating a Stereographic Panorama – the Basic Idea”

A photographic print of this sold on RedBubble in October 2011. It is an image that has always been popular at my physical exhibitions and has sold many times as a small framed print and twice as a 30″×30″ print mounted on foam board.
History of Grianan
Grianan of Ailach Fort is an Irish National Monument in the care of the Irish Office of Public Works.
There has been a stone structure on this site for more than two thousand years. It appeared on a map of Ireland made by Ptolemy sometime before 200AD. That stone structure was in turn established amidst an earlier circular hill-top earthwork also consisting of concentric rings.
