It is impossible to capture the majesty of the Ash cave on a camera, pun intended. You need to be wider than 10mm (16mm on the cropped sensor). Trying to snap it on that phone with the blinkered view, Fughedaboutit. Don’t waste your time and memory, on the phone that is.
The best way to experience the cave is to be present there in person and soak in its beauty. However, for starters the photograph below should suffice. 🙂
