Welcome! I am Roy Cross, Professor of Film Production at the Mel Hoppenheim School of Cinema in Montreal, Canada. Here you will find my research as I explore non toxic, eco-friendly options for processing motion picture film. I hope the site will provide inspiration and guidance to those filmmakers and artists who wish to begin or continue to work with emulsion. I also hope that it will provide a forum for sharing ideas and knowledge by those seeking safe and sustainable methods for continuing their artisanal practice.
