Rudolf lives on the Island Hundvåg, 5 km north of downtown Stavanger, and just at the seafront. Approximately once a week, he leaves his house with a camera in his hand and a diving tank on his back. Rudolf seems to regard Breiaviki ( the "Broad Bay" ) as some sort of extension of his garden. Many bypassers on the path along the sea may have wondered about the bubbles and flashing light out in the water late at night, in good weather or in gales.

He is married to Sigrun, and together they have two sons, Håvard and Øyvind. By occupation, Rudolf works as an engineer in the oil industry.

Rudolf has always been interested in the ocean, and the creatures you find in it. He started diving in 1980, and diving has since then been his great passion . He has dived in most parts of the world, but he actually prefers diving in Norway. Among the different stages in Rudolfs career as a diver, he has been a member of the Norwegian Clearance Diving Team in the Royal Norwegian Navy, and IANTD nitrox diving instructor.

In 1989, he purchased his first underwater camera, and has since taken thousands of photographs. He is a regular writer and photographer for the leading Norwegian diving magasine 'Dykking', and has seen his pictures published in books, articles, advertising material and various publications in addition to the nature photographs.

Rudolf's main speciality is mixed gas diving. As early as 1996, he photographed the wreck of the steamship (D/S) TINN, which rests at a depth of 100m in lake Tinnsjø in eastern Norway. The utilisation of mixed gas has enabled him to photograph marine species that are unavailable by the use of "ordinary" diving equipment. In total, Rudolf has logged more than 2000 dives, which equals 2 dives a week for 20 years. Few leisure divers in Norway have such a broad experience.
