RETOLD Training in Berlin

Retold is an EU cooperation project where EXARC and partners develop a method for open-air museums to document, digitise and share their stories. One of the avenues is that we create 3D models of the houses in these museums. These models are then dressed with all kinds of information. Our specialists from Nuwa Ltd have developed most of our approach.

Early July, they visited Museumsdorf Düppel in Berlin, Germany for a photogrammetry training. We used a small shed as a starting point. Of course you cannot simply go out there and shoot almost 600 digital pictures and throw them in the Reality Capture software, short term planning is vital, the right light (weather) and choice of the right subject matter. In open-air museums, the houses we need to document can be quite challenging: nothing is straight! With the right equipment, you can come a long way, and that does not have to be super expensive or professional. Once the photos were made, data had to be cleaned, but first after rendering, one sees where information is missing. That is why we went back and took some extra photos. This iteration was very welcome.

After only two days, the staff was trained well, so they now are able to make 3D models on their own, understanding all steps in the process. Besides that, they now have a detailed 3D model of their shed. EXARC was included in this visit to Berlin for some strategic conversations on how to proceed with the project as well as seeing things progressing in person.

In the context of photogrammetry, we also delved into related areas necessary for digitization, including the training of museum staff in Documentation Instruments & Strategies and Immersive Media & 3D Storytelling. One area of focus was 2D media, specifically still photography, which is a valuable tool for documenting static objects such as tools, environments, and groups of people involved in various activities. Within museums, still images are instrumental for everything from preserving artifacts to supporting education and outreach efforts. Additionally, strong photography and videography skills are crucial for creating 3D models through photogrammetry techniques. 

The training further emphasized documentary video production for craft documentation and outreach. In the RETOLD project, 5-15 minute documentary videos emerged as the most suitable format for capturing craft processes. This format is particularly well-suited to open-air museums, which often feature dynamic exhibits, including living history displays, natural landscapes, and craft demonstrations. The collected insights formed part of the White Book on digitization. For further information, see 2D Media: Photography and 2D Media: Video.
