The foundation DDNZS (Duik de Noordzee Schoon) are a group of passionate sportdivers with a mission to clean the wrecks of the North Sea to protect marine life. Residual fish lines and nettings continue to fish decades after they are lost. Klaudie Bartelink, one of the founders, is a professional photographer and camera(wo)man and she made a lot of films of the wrecks they have visited. Although the footage is of high quality and a good visibility of the North Sea, it is very hard to make a model of the images and films. The main raisons are: 1) the footage was not meant for 3D imaging which means data is not structural taken (not enough overlap and a lot of secundary objects such as divers), 2) the abundance of marine growth and fish which confuses Agisoft and 3) the timelapse between several dives (changes of the wreck and of the light, marine growth etc..). This wreck was a 19th century steamship which has been identified by Erik Bronsveld (Scheepswrakmysterie ontrafeld in de Nederlandse Noordzee).
