I have reworked the 360° panorama pictures – except for one. Here is the first pictureI took from Duhnen, which shows the spa areas. Furthermore, I adapted and optimized the export function in Lightroom. The quality of the 360° pictures has clearly improved.
The momento-experiment is over and I host the pictures here in my own area. I am aware of the memory the post uses when opened, but the image quality is worth it.
