Walk Carlsbad Cavers National Park's Big Room

If you've always wanted to see this remote National Park or if you're heading that way this video takes you on the self guided 1.25 mile loop trail of the Big Room. Unlike most of my videos, this one has little narration- just music and walking shots of this incredible cave. This was shot with the Sony a7sIII in 4K with only available light. ISO’s up to 80,000 we’re used though the average was 25,000. The amazing low light / low noise capabilities of this camera made the video possible. No post production noise reduction was used.
