I was thinking of shooting a few wet plates eventually with my 4x5. I see you can buy them precut and ready to shoot on etsy, the zebra kind. I just have a few questions: I see most people indicate you need a dedicated glass adapter for it. I just have regular 4x5 sheet film holders, the old wood kind. Also, can you use a safe light when developing in the darkroom? I already saw a video on it, but I would not be making my own wet plates, just developing. What ISO are they around?
