Hi guys, I am currently finishing my little darkroom. As I have decided to also try printing and alternative techniques like collodion, platinum and others, I think I will need a very good ventilation system. I have to rely solely on ventilation as there are no windows I could open - only the door but that leads into our workshop with lots of (saw)dust... Can you recommend something? What do you use and are you happy with it? All help is very much appreciated Thanks!
