Düsseldorf is underestimated in many topics. The city is neither pure metropolis nor province. It is clear enough for local observations to stick, and large enough for patterns to form.

For an independent archive, Düsseldorf is therefore a useful test case. If a motif appears there several times, it can later be compared with Berlin, Cologne or Hamburg without rushing into grand explanations.

Transition spaces are especially interesting: the Rhine, the station area, the Media Harbour, old commercial sites and quiet residential streets. There, everyday life, technology, light and memory mix.

A regional page for Düsseldorf helps with later internal linking, but also with sorting: which observation belongs to the city, which to the topic, and which only to a single evening?
