Just curious if anyone has shot paper negs with their Speed/Crown Graphic 23? I'm cleaning up my camera and will probably use the 120 rollfilm holder most of the time. But I do have some sheet film holders. These days there isn't much selection in 2x3 sheet film anyway. If I am experimenting and cutting material down for the 2x3 holders, I am thinking of trying paper negs. Anyone have recommendations for this little adventure? From what I've read, sounds like Ilford MG IV rated at ISO 12 might be a good starting point?
