Very nicely done, thanks for sharing that. What ISO, aperature, and shutter speed were used?
Great light!
Looks very nice and practical. 
The cave looks like fun too. It’s a shame the mountauns over here are so far away.
Exposure data:
ISO 800
time 4s
aperture f3,5
I used Pentax WG-2 waterproof camera in “night scene” mode and on a small tripod
Thanks for that, my last cave shots did not turn out so great, your focus seems nice and sharp. I’ll give those settings a try next week when I get another chance.
Was that camera auto focusing or did you manually focus?
I set manual focus to infinity and drive mode to 2sec delay.
Thanks, I’ll see if I can improve on the next set of cave beamshots I try.
