Data acquisition for archiving in the 3D digital era.

We can now easily generate 3D models using digital cameras, thanks to recent advances and widespread use of photogrammetric techniques. Although photography for generating 3D data does not require any special skills or tools, it does require knowledge of photography for 3D rendering, such as the use of single focal length lenses, lighting for shadows on uneven surfaces, and adjustment of white balance. In the future, it is necessary to collect photographic data assuming that everyone will be able to handle 3D data, and it is essential for the development of digital archives to cultivate human resources with knowledge and awareness of 3D rendering.
