Ten-Years Ago (22-November-2007) — Hawaii

Hawaii Photography Workshop with Thom Hogan: Day 5

While we were out on our morning photography composition lesson, I found this black volcanic rock with yellow-green sparkles. I brought it back to the lodge where I had a macro lens, and spent the afternoon trying to get some pictures of the crystals. Later on I discovered that the crystals were a semi-precious gem known as Peridot (Pele’s Tears).
