red filter: can there be too much red?

Hello,

sorry to bother with this basic question, but hopefully some experienced person could help.

I have Sony HDRHC1 camcorder (HDV) in SeaSea housing with Raynox fisheye and just have learned (painful way...) that a redfilter is needed.

I bought already one, B+W 67mm dark red filter; and now wondering once it is very dark red; should I bought less red filter? I haven´t edited yet videos, so I can not name any editing SW to use.

So, I am just wondering, is it better to take too much red on shooting (max on 30m) and later reduce it while editing, or should I take normal (or light?) red filter instead?

Thanks a lot for all advices! :-)

BR, Matti
