I never dived, so I have no RL experience. The only comparisions I have are TV
documentations. But good renderings of underwater scenes are "The Guardian" by
Johnny Yip, the winner of the POVCOMP-Competition 2004 of course, and a picture
by Glenn McCarter from the IRTC-round April 2009 "Galleon's Reef". The source
for the first is still available (follow the links at the POVCOMP site). The
source for the second is lost, since the IRTC sources are only available now for
the first phase up to 2006. Glenn had published the sources 2009 and I still
have them. Fortunatelly he had published the sources under a cc-license, so if
you will have them I can put them into the p-b-sf.

Best regards,
Michael
