Swiss CdV Landscapes & buildings

In the early days of photography, it was impossible to take a photo outdoors far away from a darkroom, because you had to develop the plate immediately. But then there were small mobile darkrooms that you could take with you on a wagon or pack animal. Apart from the weather conditions and other circumstances, the effort was very great and probably the success was rather small. And traveling around with the toxic chemicals wasn't very easy and unhealthy either.
