underwater

Hmm could someone tell me the fog details I need to create the look of being underwater?

thanks

Well your going to want blue fogish color, maybe with a grayish tint in it also to account for darkness, then use the envirment Rays of Moonlight. I am not sure if you can lower very far under water it might take some experimenting...

I know to use blue fog, hmm do you think 35% density would be good? I can never get fog right.
