My interest in photographing rockface is an old one. In the past, I've been eager for close up: one memorable afternoon I filled my camera card (the only time this ever happened in one shoot) peering at 5 sq cm portions of the South Jemison cliffs. My new camera has inveigled me into the wider view – after all, with 21 megapixels, if I want a close up I can just crop to billyo.

Rock hopping has given me access to new patterns and arrangements of rock. When the pools gather too many reflections, shadows and ripples for photography, there is no lack of beyond-the-splash subject matter: subtle, figurative, layered, dramatic.
