ok, so I want to start developing my own film (just B & W) and I need to know a few things. I have a space set out in my basement that has no light access and is completley dark. I just need to install a sink. I was wondering if a polypropylene utility sink would work? I also need to know what type of ventalation I need. It is a really big space that is connected openly to another room. Would I need just a fan? oh and does anyone have a suggestion for a developing tank that can develop 2 reels capable of doing 35mm and 120?
