The recent photographic show, Photokina organized an Underwater Imaging World, with a testing and diving pool in the central area. Various underwater photographic equipment manufacturers were invited to present their products in a water tank on the back of a truck with a number of observation windows added to both sides. Despite limited space in the tank, Marc Hillesheim was able to demonstrate some underwater model shooting techniques, working with a model, Anne Aselmann.

Nauticam offered their NA-NEX5 housing with a Nikonos 15mm wide angle lens for the demonstration and Nauticam owner, Edward Lai, got in the water himself to shoot the images.
