Two Awesome friends and I went to explore one of the caves that located south of the Capital city of Saudi Arabia, Riyadh. The place called (Ain Heet), it is awesome to explore, with its huge entrance and the cool air that comes from inside. Check this link for more information about the place and the caves in Saudi.
I blended three exposures manually, and I used blue LED to lit the cave to give it the coolness mode.
Hope you enjoy it :)
