Thinking of getting a gopro hero 4 silver for diving. I like the gopro for its simple to use design I plan to mount it to a tray and install the backscatter flip filter system. My question is will it shoot decent video with just the filters and no lights in 60 ft of water or less? I will eventually add lights (Any suggestions). Also, I know it is primarily a video camera but will it produce decent quality stills? Does anyone have any examples? I'm by no means a photographer but would like to capture the experience in a quality fashion from time to time. The majority of my diving is in Maine with relitivly limited visibility. Thanks for the help!
