Sandstone sea caves and Milky Way near Shipwreck Beach in Poipu - Kauai, Hawaii. During this 30-second Milky Way exposure, I used my main headlamp to "paint" some light on the rock for a few seconds. Also placed my backup headlamp on low-power, reflecting off the back cave wall to provide a bit of warm light from inside.
