Shot this video in 4K at 60 FPS D-CINE mode with ND16PL filter [until I crashed and lost the filter :-) ] and edited with increased Saturation and only a slight bit of increased Contrast. No other 'corrections' were used. I am disappointed I did not get to the main lava tubes. I was hoping to get a shot flying through the biggest tube, but....was not to be. Next Time!!
