Fun this afternoon playing with my adapted Voigtländer Avus and three month old Poe Boy collodion. I’m using quarter plate glass from some old glass plate negatives I found in a junk shop. I scrub the plates down and re-using them when the fail. I intensify successful ones for a couple of minutes with Ilford Selenium toner at 1+3. I’m using this camera enough now to warrant making a proper focussing screen for it.
