does anyone know a) what color temp most manufacturers use for their "underwater" settings; or  b) what do you suggest for color temp when you cant do a custom WB? I am shooting RAW so I know it is a moot point for stills but was wondering about using a compact camera to shoot video where I dont have the option of RAW and have only limited light source, i.e. sola 500,effective only with very close objects......mahalo...peter
