nyprrthd:13X,
Great, clear shots! I happened to have found an add-on for Adobe Photoshop (version 7.0 or higher) that restores the reds that are lost at depth. I "corrected" the photos of the nurse shark, and the diver near the wreck, to show you what this fix can do. I didn't do any tweaking of the color, brightness, or contrast, but I've also done that after correcting the blue out. If you have any use for it, PM me and I'll email you the info. I did them as attachments, because I still can't figure out how to add photos to the body of a post. Click on the thumbnails to see a bigger version.
Where does one get that plugin and what is it called?
