This image is about 12 years old. I captured it with a Nikonos V, 35mm lens and a 1:3 extension tube aided by a single strobe, using Fujichrome Sensia II 100 ISO transparency.
The location was one of Sydney's best muckdives in the Port Hacking River, called Shiprock. The place is only diveable about half an hour before and after the tides. At high tide, visibility is best, and that is when the divers flock to it.
The creature I initially captured was the colorful nudibranch, Ceratosoma amoena. Only after having taken a few images of this gorgeous slug, about 3" long (75mm) did I realize it was sitting atop a scorpaenid, namely a very camouflaged Red Rock Cod (Scorpaena cardinalis). Not having a TTL composing aid with that ancient amphibian camera, I had to place the framers to help me with composition and also with trying to judge the depth of field. This is my best of perhaps an entire roll of film... Oh, those good, old days.
Moderators, if deemed more suitable for the macro forum, please move the thread. Thanks. :)
Akos,
Its an amazing world down there. And pretty colourful too. I am sure with the advent of digital, it is easier creating good images of these ones than before. Thanks for sharing.
