The Deutschlandticket („Germany ticket“) was introduced in its current form as a ticket for all local public transport in Germany in May 2023. A subscription costs 49 Euros a month (soon it will be 58 Euros). It gets you anywhere in Germany that is connected to the local transport network (regional trains, busses, metro, trams, etc.).
Coincidentally, this also provides, in and of itself, some essential parameters for a photographic project. It defines a location: Germany. It establishes a time frame: Since May 2023. Or, in another word: now. It suggests a means of transportation: local public transport. In short: Germany, now, by local public transport.
