The huge, slanting rift chamber of MacKinnon’s Cave on the Isle of Mull. Ranked in the top 40 longest sea-caves in the world, MacKinnon’s has a main chamber more akin to those found in far longer and deeper potholes inland. (Nikon D7100, 15mm, f6.3, 1/30sec, ISO 400 with a Nikon SB700 Speedlite)
Several hundred feet into the cave, just before it lowers into a crawl. I visited this cave with the aim of getting very different images to the ones you usually see, so I took a wireless flash to light the cave the way I would on a full-blown caving or potholing descent. (Nikon D7100, 11mm, f.6.3, 1/30sec, ISO 400 with a Nikon SB700 Speedlite).
The entrance rift. The sea is only a few metres behind me. I placed a wireless flash a few metres to the left of the camera to ‘fill-in’ some of the shadows in the top half of the image. (Nikon D7100, 11mm, f8, 1/30sec, ISO 400 with a Nikon SB700 Speedlite).
