Does anyone know what is the present alternative for Kodak Reproduction 4566 line film and for its developer Kodak DPC print developer? Kodak apparently hasn't produced those for a long time now so what has replaced them? I have been reading a book called Experimental Photography by John Warren and in it there is an experiment called line conversion for creating images like this for example http://www5a.biglobe.ne.jp/~calcio-d/auto/che%20guevara%20kakou.jpg The broblem is that I can't even try to do it because I don't know where I can find that reproduction film or whatever has replaced it or does anything like it even excist anymore. If someone understands what I am talking about I would be very grateful for a little help. Or if someone knows better way to make line conversion please tell me. And I'm talking about making it in darkroom, not digitally.
