Hi there...
When I do under water scenes I generall use a simple coloured background made in psp which I import into poser. I either bring it in as a background or apply it to a flat square . I then play around with lights to get the effect I am looking for and then render with shadows and such on. I keep doing this until I get the overall effect I want. Then I reimport this image and use it in place of the one I first used. I can then begin assembling the scene I have in mind from there with the figures, lighting, props etc. I then render often with the depth cuing on to add a more underwater feel to the image. It take a little fiddling but pretty good underwater scenes can be achieved in poser.
