Cave photography is both a science and an art! Usually a lens exposure of around 30 seconds is used to give enough time for multiple flashes to light up different areas of the cave in order to get the correct illumination. It doesn't have to be a flash, sometime helmet lights or flashlights can be used but then the white balance has to be adjusted for the different frequencies of 'white' light that is used.

An international crew of six astronauts are training for a caving adventure designed to prepare them for spaceflight. There are many similarities to spaceflight such as a lack of day–night cycle, sensory deprivation, minimal hygiene and the necessity to work as a team and solve problems together. From left: Roscosmos’ cosmonaut Nikolai Tikhonov, David Saint-Jacques from the Canadian Space Agency, NASA’s Drew Feustel, ESA astronaut Andreas Mogensen, JAXA’s Soichi Noguchi and Mike Fincke from USA.
