Sea cave at Maori Bay, Muriwai, New Zealand. This was challenging to scan, with low light levels, reflections off the wet sand, and having to dodge waves surging through from the other cave entrance. An interesting test but it hasn't really captured the large size and atmospheric lighting of the cave as well as i had hoped. I noticed some of the graffitti on the cave walls dates back to the 1970s.
