I have attached a first try.
Covering such a large dynamic range is not simple. One key ist to modify
the base curve (raise the lower part, flatten the upper part).
The "Tonemapping" module at low strength is helpful, too.
"Shadows and Highlights" works, but has its limits. Additionally, the
dpreview image appears to be processed by some kind of digital graduated
density filter (look at the skyscrapers).
Colors are a bit difficult, most likely one needs to use parametric or
drawn masks to handle shadows and highlights differently.
Regards,
Markus
