Deer Cave in Gunung Mulu National Park (Borneo)
Deer Cave is a passage about 150 m (500 feet) in diameter and about 1 Km (0.6 Miles) long, opened on both end. It was, for many years, considered the largest single cave passage in the world.

Photo processed in True Tone HDR with Tone Mapping from 3 RAW exposures.
Unfortunately the photo has quite a lot of digital noise, because i did not have a tripod high enough, so i had to take all 3 exposures hand-held at high ISO. The HDR processing also tends to increase the noise. If i could have used a tripod to get low-ISO long exposures, this photo would have been outstanding. It's one the best photo of Deer cave that i have seen so-far.
