The "Gigapixel VR Gallery" is an opportunity to view extremely high-resolution pictures in various sizes exactly up close in 6DoF (images can be found on https://gigapixel.gmbh/en/).
The gallery has 48 motifs ranging from 136 megapixels to 15.9 gigapixels. One gigapixel is 1000 megapixels. There is also an option to switch between the high resolution with a resolution of 25 megapixels. This helps to understand what influence the distance to the image has for qualitative perception. The closer you are to the subject, the more important it is that the resolution is high enough.
One square on the floor equals 1m².
This project is more a matter of the heart than somehow making money professionally.
