Cadair (sometimes 'Cader') Idris rises near the southern limits of the Snowdonia National Park in Wales, overlooking the Mawddach estuary and Cardigan Bay. A buckled ramp of the long ago eroded Harlech Dome, its Ordovician rocks are some 450 million years old. It has a long scarp facing north, and was sculpted on all sides into cwms (cirques, or corries) during the last ice age.

I grew to know this mountain through seasons and years, and the engagement tutored my vision. The whole is composed of details. The seeing eye notices movements, stillnesses - the interaction of light, air, water and land - the air is tactile, the acoustics alive, and the universe obviously in motion. Not just the senses, but mind and feelings, become keenly awake. Wild places don't need us, but their purity of being - their 'is-ness', is a vital reference for the feeling mind. Although wilderness is everywhere, even within ourselves, on mountains and by the sea we may find a rugged witness in the rock that refers us to more ancient times - towards our cosmic origin in a very physical way. Allow yourself to be alert but still in such a place, transparent to what's around you, and perhaps some of the world's breath of being can be felt.

The images represent facets of an emotional and spiritual response to place that is personal but may also resonate more universally. The framings are intuitive - there is no artifice, and if some of the results at first seem enigmatic, this is incidental but may be useful - look again.

Factored into the intuitive process is knowledge of how light, lens and film interact.
