Jonas Pedersen has shot this surreal and beautiful video of diving the cave system at El Toh in Mexico’s Yucatan. The video was shot on a Sony a7s in S Log 2 and set at between ISO3,200 to ISO50,000. The image is stunningly clean, showing just how amazing the low-light performance of this camera really is. The camera was housed in a Nauticam housing, and lighting was from Halcyon and Gralmarine.
