Ken is right. If you can take one you just have to duplicate it. When I started I had a notebook with me and wrote down Fstops, Shutter speed and film speed. Untill I got the hang of it I could look back at the ones that worked and do it again.
The good news is that I think aquarium photography and corals in general are really hard to take photos of. You have to balance lighting, movement, and depth of field to get a photo to be proud of. Plus if you are like me and have a plexi tank you have to shht dead on or suffer from distortions.
Reefbass makes it look pretty easy, but I am sure he will tell you it took a little practice.
Reefbass took a look at your website and it looks great. I love the black background. I tried all sorts with mine and settled on a
Green tint. Nice pic also.
Clay don't give up and if you need help let me know...Craig.
