Caving in Ogof Ffynnon Ddu cave - cave of the Black Spring. OFD is inside a mountain at Penwyllt in the Upper Swansea Valley in South Wales and has over 50 kilometers of passages. Saturday I photographed a group of cavers, climbing and squeezing their way through the cave. Photography in a cave environment is always a challenge, physically protecting the camera equipment from mud, water, grit, sand and getting bashed, and having to carry all equipment while caving. We had a few novice cavers with us, so there wasn't time to set up lighting and pose images as they might have got cold waiting around, so these pictures had to be taken quickly, while the group was on the move.
