I've only used my two underwater cameras in pretty shallow water. I have a TG4 in a housing and a Nikon P7100 in an Ikelite housing. I have a 1500 lumen video lite and a backup 650 lumen light on the other arm. Do I still need a red filter? If I'm "bringing my own light" then do I worry about loosing the red even though I'm using video lights? Thanks for any help!
