Lyndon, Best results are obtained by placing the light source away from the camera. Backscatter is a big problem underwater of course, but even in humid/moist cave environments this is going to be a problem, a bigger problem the further the object is from the camera. So the rig you are thinking of would be good in a small cave, but not very effective in a larger one. That camera would be great for open pit rappelling in daylight...AYYYYHHHHH

The beautiful circular rotunda shaped ceiling can easily be seen. Here, the third chamber is illuminated primarily by one Meggaflash PF330 flashbulb. These extraordinary bulbs burn for nearly 2 seconds, producing a brilliant light. The only way the grandeur of this room can be fully appreciated is when these bulbs are fired. Applause broke out after this shot was completed! Communication between flash runners and the camera operator is practically impossible--echo muddles all conversation. So, to help with this delima, we utilized Motorola personal two-way radios to keep things going smoothly." -- Lyndon Tiu --------------------------------------------------------------------- Visit our website: http://texascavers.com To unsubscribe, e-mail: texascavers-unsubscr...@texascavers.com For additional commands, e-mail: texascavers-h...@texascavers.com --------------------------------------------------------------------- Visit our website: http://texascavers.com To unsubscribe, e-mail: texascavers-unsubscr...@texascavers.com For additional commands, e-mail: texascavers-h...@texascavers.com
