The Source images were shot on a 16mm Fisheye Zenitar lens.
Glencolmcille is a classic, flat-floored, glaciated valley. Surrounded by the hills of South West Donegal, the the mouth of the valley opens into the North Atlantic with a gorgeous sandy beach.
The Church of Ireland church sits in the middle of the valley floor with a commanding view of the whole of Glencolmcille.
There is an underground chamber or souterrain in the grounds just in front of the church. It is thought to have predated the current church by many centuries and to have been used as a place of sanctuary in times when the valley was attacked from the sea by Vikings raiders.

History of this Image on RedBubble
This HDR (High Dynamic Range) panorama was created by combining 27 separate digital photographs covering every angle and with bracketed exposure. Hence there is detail both in the brightest parts of the sky and in the shadows.
The Source images were shot in sets of three bracketed (+/- 2 stops) Raw exposures on a Canon EOS 5d DSLR with a 16 mmm fisheye lens, and were stitched and blended using Hugin – a free open-source panorama stitching program.
Hugin in turn invokes a program called Enfuse to achieve the HDR effect, by blending the best exposed parts of each of the images in each bracketed set.
