Within the framework of the project, Bela and Hagren have attempted to locate the glass negatives for these images but have only found paper copies. When searching through the Upplandsmuseet archives, the artists discovered an old greenhouse window, said to be constructed with Osti's old glass negatives. In the Upplandsmuseet archive, the following information is provided: "The glass window has been in a greenhouse. At the beginning of the century, it was common to wash glass plates clean and reuse the glass in greenhouses and hotbeds in botanical gardens and agriculture.
Bela and Hagren have still been unable to find Osti's glass negatives from the cloud atlas, neither in Carolina Rediviva nor Upplandsmuseet's archives, and they wonder if Osti's significant contribution to meteorology may have been washed away and sold (negatives with clouds as motifs may appear abstract and uninteresting compared to cityscapes and portraits).
In Ivar-Lo Johansson's novel "Godnatt Jord," / "Goodnight, Earth," there is a fictional character who buys used glass from a closed photography studio. The story could be inspired by the fate of Osti's glass plates.
Hagren & Bela have produced cameraless images by utilizing leaves as negatives in the darkroom, creating microscopic enlargements of the structure of plants. These abstractions of nature photography are mounted in frames, constructed in reference to hotbed windows from the early 1900s.
