Most of the photos posted to this page were taken with a Canon 20D in an Ikelike housing with TTL connection to an Ikelite DS-125 and an Inon 2000 substrobe. I also use a Sony Cybershot P150 in a Sony housing attached to a Sea & Sea YS-25 via fiberoptic cable.
Here's another photo of the Blue Ringed Octopus.
