Everything I learned about handling liquid emulsion and darkroom-printing on tricky surfaces like concrete, stone or glass. Covering coating of the emulsion, the photo gelatin choice, the melting setup, red safelight choice & more. I used the Adox Polywarmtone emulsion, but you can use any you can find - Rollei, Foma etc.
The images (and concrete!) are from a construction site I've been following since two years. The book of my first construction site - https://www.fotoimpex.com/books/bookmagazine-buchzeitschrift-history-under-construction.html
