I finally got around to uploading some of the footage I shot in Mexico in Feb and May of this year ...
Temple of Doom (Aka Calavera) -- Madonna & Canyon Lines
Nohoch Nah Chich (Giant Birdhouse)
And Dos Palmos (Downstream towards Cenote High voltage)
All shot in an FX1 with dual 50W lights. The Nohoch video also used an 18W light held by the diver, but I dont think it was hugely effective so I will be trying the 24W handheld HIDs in November.
