I have received a donated Leica Focomat V35. John Doane sent it to me, to help rebuild my darkroom after Katrina. I am eternally grateful to John for such a wonderful gesture, and to everyone else who's kind words a donations have helped us tremendously. I am looking online for help printing B&W with the color head. I mean to say what filtration is need to equal a 2.5 multigrade filter? Is there a chart available somewhere. Any help would be appreciated. I am very excited at the prospect of printing at my own leisure and pace again. I am using a public darkroom wich is VERY nice but its not the same. If I get tired or frustrated I have to motor on, can't just put things aside and wait for the creative juices to start flowing again.
