The Gaia Exploration Club in cooperation with the Protected Area Management Board and Palawan Speleological Guild (PalSpeg) continued its annual Cave Management Planning and Expedition in Puerto Princesa Subterranean River National Park last 27-31 December 2019.
One of the activities conducted was the photo-documentation of the 150 Year Gallery to the Magellan Chamber including La Carlita Branch through macrophotography. This technical type of photography allows the documentation of cave formations deep in the PPSR so that it can be shared to cave enthusiasts, geologists, and biologists, among others. Macrophotography inside the Magellan Chamber was challenging because of the extremely dark cave environment. The photographer must have the technical knowledge of how to manually operate the camera to capture vivid photographs of cave formations.
Below are few examples of what GEC President Mark Dia photographed during the December 2019 expedition:
