At the Mythos Natur exhibition, using the audio guide (German only, I think): there is a definite arc through the selection. Though I was confused by the hanging, which often defied chronology (I enjoy seeing how an artist's style or approach changes over time, without having to hop to and fro), I was frustrated by the lack of ambient lighting (to consult the leaflet for names, dates or painting techniques), and dismayed by the lighting, which often did not include the framing (which is surely part of the presentation) and sometimes cast shadows from the framing on the painting. But I did learn a lot, and was left with new ideas and a better appreciation of the topic.
